Facebook is reportedly working on incorporating the hashtag into the social network.
Facebook has plans to bring the hashtag to its site, offering everyone the ability to index conversations around a particular topic, just as they currently do on Twitter. Sources ”familiar with the matter” told the Journal that while Facebook is working on the feature, it wouldn’t necessarily be released anytime soon.
Now we will either be annoyed by the hashtags or no longer be annoyed that people write how you can't use hashtags on Facebook.
