Facebook is taking a page from Twitter again.
Nearly two months after Facebook started rolling out Twitter-like hashtags, the social network is testing Trending Topics, which tracks what topics users are talking about most on the site.
"Today we started running a small test that displays topics trending on Facebook, a Facebook spokesman told Computerworld in an email. "It is currently only available to a small percentage of U.S. users who use Facebook's mobile website and it is still in very early stages of development. We will share more details down the line if we decide to roll it out more widely."
