Public Conversations on Facebook - Hashtags für Facebook (ich hätte sie dort social words genannt).
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.
