Once upon a time, you actually had to pay attention to your friends on Twitter. Twitter did its part to make your frustration worse, asking you to follow new people at every opportunity. Twitter is rolling out a mute button across its service that will let you liberate yourself from the blabbermouths while still preserving your more delicate relationships. Hardcore Twitter users have long used the (superior) mute functions in alternative clients like Tweetdeck, Tweetbot, and Echofon — and if you’re curious why they seem to like Twitter so much more than you do, mute is a big reason why.
