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.

Facebook Adds Hashtag Support [newsroom.fb.com]

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.

We'll continue to roll out more features in the coming weeks and months, including trending hashtags and deeper insights, that help people discover more of the world's conversations.
