Hashtags, the all-but-ubiquitous topic organization system found on Twitter and other services, are coming to Facebook.
They will roll out to a small percentage of users on Wednesday and expand to more users over the coming weeks, according to Mashable.
According to Facebook, many users already post hashtags anyway, so why not make them work. Hashtags will be both clickable and searchable, so, for example, topics like #NSALeaks or #NBAFinals will now exist.
Hashtags from other services, such as Instagram, are clickable as well. Users will also be able to compose posts directly from a hashtag feed and search results. That could make adding real-time content to specific streams easier than before.
