Facebook Working on Incorporating a Twitter Style Hashtag

The Wall Street Journal first reported that Facebook is working on incorporating the hashtag, one of Twitter's most iconic markers, into its service by using the symbol as a way to group conversations, said people familiar with the matter. It is unclear how far along Facebook's work on the hashtag is and the feature isn't likely to be introduced imminently, these people said.

Facebook is testing whether to follow Twitter's lead and allow users to click on a hashtag to pull up all posts about similar topics or events so it can quickly index conversations around trending topics and build those conversations up, giving users more reason to stay logged in and see more ads. Instagram, which Facebook acquired last year, already uses hashtags, allowing users to sort photos by the symbol.
