Bit more analysis here. 'Scuse the c&p but there's a lot to cover (and there's loads more on the page)
What has Facebook announced?
Essentially, there's three or four main areas, depending upon how you look at it, as well as a bit of a bonus which wasn't so much unveiled as just laid down as a little tester. They are as follows:
1) Social Plug-ins
This is probably the easiest part to get a handle on. What Facebook is doing is offering a bunch of social plug-ins as a way of other websites to embed widgets on their own pages with direct and often live access to what's going on in Facebook in relation to the site that you happen to be looking at.
If you go to CNN's homepage, you can see an example of this right now. Look to the right of the screen and you'll see the Friends' Activity plug-in which can direct you to other CNN pages which one of your friends on Facebook may have shared on their Facebook profiles. It's a clever way of making the content of another website more appropriate to each individual viewer.
Another of the plug-ins can be seen on IMDb where all the pages have a Like widget, just the same as the ones you would see on Facebook itself next to friends' comments and updates and such. If you Like another page, it'll work in much the same manner with that page then appearing as a link on your profile.
Essentially, the Like feature of Facebook suddenly becomes a powerful Digg-like tool - a recommendation engine for other websites.
That said, there is a separate Recommendations plug-in to be added as well. This will appear in rather the same way as the Activity Stream but will be regardless of what your friends have shared. Instead, it will suggest relevant content based on the site you're looking at. Whether those links will take you to other sites or not has not been stated.
The Log in plug-in (yeah, a mouthful, that one) is essentially a re-branding of the Facebook Connect scheme which merges your membership of sites with your Facebook profile as well. You'll be able to hit the Log in widget on another site which will then give you information from your Facebook network as well such as all your other friends that are also registered for this site.
The final plug-in is the Social Bar which will show your friends who are also on the same external site as well as allow you to chat and show the Likes within your network for the pages that you're on.
2) The Open Graph
Slightly mind-bending, this one. So, the best thing to do is not think about it too hard. The Open Graph is a social platform that Facebook is intending to turn into a more intelligent way of searching the internet. At the heart of it is the idea of the semantic web which is all about offering an individually relevant set of search results based on the user doing the looking - all this rather than the traditional approach of chucking in a search term and getting the same results as anyone else would who happens to be using Google.
The latter method relies on how the search engine happens to have ranked and indexed all the pages, whereas the Open Graph intends to present pages based on you're more likely looking for or might want to see.
Facebook, of course, has a massive user base of 400 million people and how they relate to each other. The Open Graph platform is going to add to that all the relationships you have with objects as well, be they web pages, restaurants, music, films or whatever and all based on what you've shared and Liked and all the apps you use.
Through that, Facebook can work out an almost complete social map of your personality and how strong your feelings are towards each of these connections to offer a more relevant search for you. Very ambitious indeed.
