Today was f8, Facebook's conference for announcing upcoming developments. Among all of the features talked about, what had me most excited were the "Social Plugins" they've announced. As of today you can now go to a number of websites, including this one to see new ways of sharing information with friends.
One of my favorites of these social plugins is the new "Like" button that can now be added to any website by a developer in which users can click on it and it will not only tell people at www.facebook.com that you liked the page but it will also show you what other friends who were there previously have also liked it. Check it out, go to imdb.com, look up a movie, an actor, a tv show, and you'll see a facebook plugin with the "Like" button. The buttons at IMdB will also add movies and tv shows you like to your favorite movies, so rather than having it show up that you like something in your feed for a few short hours, it edits your profile information to make it more permanent for others to look at.
Other social plugins provided by facebook include a live stream from a facebook page, ability to add comments to a page, a login box, recommended pages to visitors, and more. If you would like like to take a look at or maybe add some of these features to your site like I have, head on over to http://developers.facebook.com/plugins for more information about what these things do.
