Hashtags were rumored to be coming to Facebook earlier this year, but the site officially announced that it has added support for the popular Twitter and Instagram staple. Now whenever a Facebook user puts a hashtag in their status update or comment, it connects it to others talking about the same thing.
For instance if you leave a comment on a post, something like “Go #Sheridan #Internet”, you can then click the #Sheridan or #Internet hashtags and see the discussion around the keywords on Facebook. This could be huge for Facebook’s Graph Search, which will now allow users to search by keyword.
Several users have reported that hashtags aren’t linked yet, so it appears that this is a gradual rollout by Facebook.
