Does Facebook Really Need Hashtags?

We’re not looking to discover real-time content on Facebook. They clutter up the design. So why add them? Firstly, the same kind of “me too” behavior that led Facebook to rename “subscribers” — people who receive your public updates but aren’t actual friends — to “followers.” Many people post their Twitter updates to Facebook automatically, so the social network might as well utilize the hashtags in those tweets.

The second reason is a common one for Facebook engineers, whose slogan is “move fast and break things.” Even if a user does only use hashtags once in a blue moon, they will help Facebook learn a little bit more about that user’s likes and dislikes. This enables the social network to serve you more targeted ads. (Advertisers can’t buy hashtags yet, but have no doubt: that’s coming.)
