Facebook announced a few Platform updates, including updates to the Live Stream Plugin, Liked articles appearing in search results, and improvements to real-time updates.

The second one is in line with a feature the company was testing that we mentioned recently. "Consistent with how we treat other Open Graph object types, we’ve introduced the ability to see articles shared by your friends in the search typeahead," says Facebook's Namita Gupta.  "For instance, if your friend clicks 'Like' on an article at a news site, the article will appear in your News Feed and can now also surface in the search type ahead."

The results, as AllFacebook described upon finding the feature being tested, showed content based on the number of likes and the number of friends who liked the particular object. "The search results have now become dramatically more relevant with the inclusion of recent news articles, something that previously wasn't accessible via Facebook's open graph search results," AllFacebook's Nick O'Neill had said. "Currently, the search results only appear within the drop down from Facebook’s search box, however I’d assume that this will eventually shift to Facebook's search area, which has yet to undergo a significant overhaul."

Either way, there is clearly a direct connection between likes and search now. It's essentially Facebook's version of PageRank. 

As far as the other updates...

"We recently began supporting real-time updates for page updates and the following object property types: relationship status, significant other, timezone and locale," adds Gupta. "To support developers building with users' location data, we've also introduced the ability to subscribe to check-ins. Like all objects available via subscriptions, developers can only retrieve updates to check-in data after a user has the granted permission."

Facebook is rolling out the Live Stream plugin for all new and existing apps, as a way "to be more consistent with users’ expectations and other social plugins." All posts can now be seen in real-time by other people viewing the Live Stream. Facebook is also adding the option for users not to share their comments on Facebook. In addition, it now supports multiple Live Streams on one site by specifying a URL, which will link status updates to their respective pages.
