We’re hearing that iTunes will be implementing Facebook Connect support in the near future, allowing users to share some of their recent purchases with their friends on Facebook. We’re still gathering more details, but it sounds like this could happen quite soon.

It certainly adds up. Over the last few weeks, iTunes has been building out its Facebook Page at Facebook.com/iTunes, which now includes polls, featured items, and is being promoted in iTunes itself.  And Lala, which was acquired by Apple in December, has extensive experience working with Facebook Connect (they also power Facebook’s song gifting feature).

To be clear, you can already share songs on iTunes using both Facebook and Twitter (the feature was introduced last September). It sounds like this integration would make this easier, and there’s obviously the possibly for Apple to leverage Facebook’s social graph in much more interesting ways in the future.

Apple has previously worked to add Facebook support to other apps — iPhoto includes an integrated Facebook photo uploader.

MySpace is preparing to add Facebook Connect features to its main service, we’ve confirmed from a source within MySpace. This will be the first time MySpace will publicly conceded defeat to Facebook over ownership of the social graph, and it’s more than a touchy subject internally.

So touchy, in fact, that my source tells me that by simply breaking the news early the whole rollout might be ditched or delayed. A key part of the launch is apparently a serious amount of message massaging by MySpace PR on what this means for MySpace.

Earlier this year the MySpace UK team added Facebook Connect features to a fan video without, apparently, the knowledge of upper management at MySpace. MySpace also quietly (silently actually) rolled out sharing on Facebook for MySpace videos recently. This new Facebook Connect rollout is being done very quietly as well, we’ve heard. Some very senior MySpace execs seem to have no idea it’s happening.

So what does all this mean? In the next week or two we’ll see at least a limited rollout of Facebook Connect on MySpace. Or, we won’t. Ah, the joys of having co-presidents to take your company to the next level.

There will be lots of news leaking about Facebook’s product announcements at their upcoming F8 Developer Conference in April. That’s because they’re already starting to test out a lot of the new stuff with third party developers, and once two people know a secret, it isn’t really a secret any more.

One of the new features we’ve been hearing about is the extension of Facebook Connect and the Facebook API to allow publishers to add a “Like” button to any piece of content on their site.

Sound trivial? It isn’t. This is likely part of Facebook’s Open Graph API project that will incentivize third party sites to interact deeply with Facebook by sharing content and associated metadata.

Today you can “share” content with Facebook via a simple button (you can see our implementation at the top of this post). The new Like feature goes way beyond the Share button, we’ve heard.

Good for publishers? Yes. But it’s also very, very good for Facebook as hundreds of thousands of websites will rush to format their content to exactly Facebook’s preference and send over all their data without a second thought.

One way to think of this, says a source with knowledge of the product, is this. Google spends billions of dollars indexing the web for their search engine. Facebook will get the web to index itself, exclusively for Facebook.

Yes, it’s a big idea. Or, as MG put it, the entire Internet will be turned into a tributary system for Facebook. And it all flows from a simple Like gesture, and a few other features we’ll be writing about shortly.

As has been made abundantly clear to me over the past two weeks, just about every location-based service is planning big things for the SXSW festival, which starts later this week in Austin, Texas. A few of the players have already started rolling out small changes, such as aesthetic upgrades. But a new, subtle update by Foursquare may have much larger implications.

As we noted last week, Foursquare has begun revamping the “history” area of its website. This is likely part of the larger goal to completely revamp the website itself (which isn’t very useful right now), and this data also ties in to the new Foursquare iPhone app set to launch later this week. But another update makes the history area show not only where you checked-in, and the category of the venue, but also who you checked-in with.

Basically, Foursquare has just turned on a new layer to your location history data. And this layer is very interesting because it goes back in time to show you who you were with at a certain venue when you were there.

Now, to be clear, it only shows you the friends you were with — not all Foursquare users. (But this means that they have that data as well.) Still, this data paints a clearer picture around your location history and potentially enriches your social graph. It’s one thing to say you’re “friends” with someone on a social network, but another to have checked-in to the same venue at the same time over and over again. Either you’re torturing yourself, or you really are good friends with that person.

This is a huge part of location as the bridge between social networking and actual social activity.

Foursquare has highlighted similar data for a while on the stats page, showing you who you check-in with most often. But this new history data takes that to the next level. And while the data right now only seems to go back to last December or so, Foursquare plans to implement it all the way back to 2003 — yes, 2003.

That’s because before Foursquare, co-founder Dennis Crowley ran a similar service called Dodgeball, which Google bought in 2006, and deadpooled last year. But users were able to import their old Dodgeball data before it went under, so Crowley now hopes to build a full location history social graph going back that far for long-time users.

“We gotta backfill some of the data (easy, but for those who imported their Dodgeball history before Google took the site down, we can give you a good idea of the trends around who you’ve been hanging out w/ going back to 2003.) It’s awesome awesome awesome,” Crowley writes in an email to us.

Something else Crowley is excited about is the potential for the visualization of this data. While this location history + friends isn’t yet in the API, it definitely will be, he notes. Depending on how that data is shared, that may raise some privacy issues, but Foursquare has made it clear that they’re well aware and very serious about the issues surrounding the sharing of location data.

Even on the most basic level, this new layer of location history data should be interesting to people. It’s great to look back and see not only where you were on a certain date, but who you were there with. That’s what social data is all about.

Now Yahoo allows you to add your Facebook friends’ email addresses to your Yahoo Contacts via Facebook Connect. In the Import Contact landing page of your Yahoo account, you’ll be able to select Facebook (importing from Gmail and Hotmail already exists). Once you authorize the connection with your Facebook credentials, your friends’ email addresses from their Facebook profiles will be added to your Yahoo Contacts. Yahoo will scan the imports and delete any duplicates.

As we’ve written in the past, Yahoo’s move with Facebook shows that the company has given up on leveraging the existing social connections among Yahoo email, address book and messenger users, and thus, weakens its ability to monetize this social graph. And Yahoo also just added Twitter integration to its products as well. While Google’s Buzz may have its problems, at least Google is making an effort to try to develop technologies that use its communications products to build a social graph. Perhaps Yahoo CEO shouldn’t bite the hand that feeds her.

Following the disastrous earthquake in Haiti earlier this year, a number of web companies have been setting up special programs to try and do their part to help. Twitter has been one of the most active, as the company has made great use of its social graph to get the word out on how to help through donations and other means. Now they’ve done something else.

Twitter was able to strike a deal with Digicel to bring free SMS tweets to Haitian citizens (who use that carrier). Previously, people in the country would be charged a messaging fee each time they tweeted, so obviously this will help them communicate with the outside world a little easier. And it’s very simple to set use even if you don’t have a Twitter account yet. As co-founder Biz Stone writes today on the company blog:

To activate the service, mobile phone users in Haiti can text follow @oxfam to 40404. Accounts are created on the fly and any account can be followed this way.

Stone credits Twitter mobile lead Kevin Thau with striking the deal. He’s also been the one behind similar deals in several countries around the world such as India, the UK, and others. This is part of Twitter’s broader plan to go back to its SMS roots to enable people around the world without broadband access or smartphones to use Twitter easily.

Facebook has acquired its third company, Malaysian startup Octazen Solutions. Facebook says this is largely a talent acquisition, according to GigaOm. Octazen has a slightly different story on their home page, saying Facebook acquired “most of the company’s assets and to employ those assets in a different direction.”

Either way, it’s leaving some people scratching their heads. Said one senior engineer at a competing company that we spoke to this evening, “Facebook just bought the web’s most talented and creative scrapers that have gotten around everyones rate limits and detection systems.” Said another person we spoke with this evening who is knowledgeable of Octazen’s product, “Facebook is so sanctimonious about protecting their own user data through Facebook Connect, but Octazen has been scraping user data for years off terms of service and then reselling it.” Both sources asked to remain anonymous.

Facebook, for their part, have not yet responded to our request for comment.

What exactly has Octazen been up to? The company is mostly about above-board contact importing from one service to another – signing in to Gmail from Facebook, for example, to import your contacts there and add them as Facebook friends. Much of this is done via OAuth and APIs, but Octazen is known to dive much deeper for data.

One example – Octazen will sometimes collect and store user credentials directly, and sign into large social networks and other sites as if they were the user, say multple souces. Then they’ll download the address book and social graph. A percentage of your friends on that service might be users of the service (now Facebook) paying Octazen, and you’ll be asked to friend them. But there’s a big question about what happens to the rest of the data as well, and if Octazen is storing a shadow social network in violation of terms of service to recommend user connections down the road. And they may look deeper at data than they should – at email header information, for example, to get a better understanding of who you communicate with the most.

But the most unnerving part of Octazen, say our sources, is the fact that they are very, very good at scraping data at scale without being detected. They may hit a service using lots of different IP addresses, for example, and remain undetected. Octazen could, they say, scrape very public sites like Twitter, where the social graph is on each profile, in a way that Twitter wouldn’t know it’s happening.

In 2007, for example, People were buying and running Octazen scripts to scrape contacts in a very sketchy way: “So we use this toolkit from Octazen to scrape contact lists off of various sites. Our ever eager users (ab)used this feature so much that hotmail blocked us.” The poster found a way to access Hotmail’s API instead of just scraping to get the data, and Octazen responded, saying “Very nice indeed”

Our understanding is that Facebook already uses Octazen to mysteriously determine your long lost friends and suggest that you re-connect with them (leading to scores of emails into our inbox that Facebook is somehow reading emails or otherwise getting data they shouldn’t be).

The big question is why Facebook would need to acquire a company located half way around the world if all they were doing is standard address book imports via OAuth and APIs, or proprietary but well documented protocols like Facebook uses. The implication is that these guys have serious expertise in data gathering at scale that may sometimes be in violation of the terms of service of the sites being harvested.

This is obviously just one side of the possible story, albeit based on hard evidence of Octazen’s shady prior practices and via multiple sources. But until Facebook explains this acquisition in more detail, we don’t have much more to go on.

Here’s a good virtual parlor game. Pick any two or three Twitter users, and Twiangulate which friends or followers they have in common. Twiangulate is a site that shows the overlap between your social graph and any tow other people on Twitter. It shows the resulting names as a list or an interactive social map.

For instance, if you click on the image at right, you will see an enlarged version of a map I made to see who I follow in common with @fredwilson and @anildash. Fred Wilson follows 463 people, Anil follows 573, and I follow 315. Yet according to Twiangulate, we have 81 common “friends,” which perhaps says something about how insular the world of Web startups and social media can be. In contrast, Ashton Kutcher (@aplusk) and I only have 15 common “friends.”

So who are some of the people Fred, Anil, and I all listen to on Twitter? Some of the common people we follow include Josh Kopelman, Chris Dixon, John Borthwick, Dennis Crowley, Doc Searls, Steve Case, Joshua Schachter, Danny Sullivan, Bradley Horowitz, Michael Arrington, and Jeff Jarvis.

Are we listening to the right people or do we suffer from groupthink? Who do you overlap with the most on Twitter?

Now, the author is quick to point out the caveats of the graph (and does so for four paragraphs), and notes that he was hesitant to even publish it because of how easy it is to misinterpret. The graph, while it shows commits, doesn’t weigh more important ones versus less important ones. Nor does it in any way measure the ways in which companies or individuals contribute to WebKit in other meaningful ways. That said, it does clearly show that in late 2009, Google surpassed Apple as the company that now contributes the most (again, in terms of commits) to the project.

WebKit is the open source web browser engine that both Apple’s Safari and Google’s Chrome browsers (among others) are built on top of. As such, it should be obvious why both are so heavily involved in the project (others on the graph include Nokia and BlackBerry maker RIM).

The graph ranges from 2007 to the present. According to it, on November 15, 2009 Google surpassed Apple in number of commits for the first time. Google has been ahead ever since, and the gap between the two appears to be growing. That said, the two big spikes for Apple came during major releases of Safari, so when Apple releases another version, it could spike up ahead of Google once again.

I’ve included a picture of the graph below (Apple is the blue line, Google is green, “Other” is purple, Nokia is gold, and RIM is light blue). But be sure to check it out on Chromium Notes’ site as you can drill-down to see more detail there. The author has also posted the code for the graph on github.
