Basically, Facebook is offering up a set of widgets — it calls them Social Plug-ins — that you can drop into any web page to make that page more “Facebooky.” There’s a Like button, a Recommendations widget that shows what other pages people’s friends are reading, an Activity Stream widget that shows a simplified version of the visitor’s personal Facebook news feed, and a Facebook Bar, a toolbar site owners can float at the bottom of the screen that serves all of these things at once.
