Hashtags For Facebook
The Wall Street Journal reports:
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. Facebook's work on a hashtag is a sign of the heightening battle between Facebook and Twitter, as both compete for mobile users and fight for advertising dollars.I guess it could be #useful.
