Facebook rolling out hashtag support
hashtag facebook

Facebook will begin rolling out hashtag support on the social network today to "bring conversations more to the forefront." Facebook says that starting today hashtags will be clickable on Facebook and "will allow you to add context to posts or indicate that it is part of a larger discussion." You'll now also be able to search for a specific hashtag from the search bar, such as #NBAFinals. Click on hashtags that have originated from other services such as Instagram and Twitter, and compose posts directly from the hashtag feed and search results.

You can learn more about hashtags in the Facebook help center.
