Facebook Makes Hashtags Official

Please do not act surprise or overreact, the hashtag has long gone beyond Twitter. 

And before you begin to push #FACEBOOKCOPIESTWITTER, you should know that; 

• The Hashtag did not originate with Twitter
• A Twitter user, not a Twitter employee originated the Hashtag on Twitter.

To bring these conversations more to the forefront, we will be rolling out a series of features that surface some of the interesting discussions people are having about public events, people, and topics. As a first step, we are beginning to roll out hashtags on Facebook.

Introducing Hashtags on Facebook
Starting today, hashtags will be clickable on Facebook. Similar to other services like Instagram, Twitter, Tumblr, or Pinterest, hashtags on Facebook allow you to add context to a post or indicate that it is part of a larger discussion. When you click on a hashtag in Facebook, you'll see a feed of what other people and Pages are saying about that event or topic.
