At Web 2.0 expo in New York today, Facebook CTO Bret Taylor announced that 2 million websites have added the “Like” button and Facebook’s other new social plug-ins, which were launched five months ago. Facebook also confirmed the stat in a Tweet. That’s impressive considering the number was 50,000 only five months ago. Facebook’s new social plugins,which include a ‘Like’ button for the web and an array of other widgets, were launched at f8 in April. Aside from the Like Button, Facebook’s other social plugins include an activity feed that displays your friends’ activity, a widget with recommended articles, and the Facepile, which shows you photos of your friends who also use the site you’re browsing.
