You can click once on any or all of the buttons, and un-click if you change your mind. The idea was to eliminate a bunch of "Me, too!" posts, but the disagree button has an entire server of wank devoted to it, which I find hilarious. It's now gotten so that the minute someone wants to know why they were disagreed with, they get dozens of clicks. The speshul snowflakes can hide any of the buttons they'd like, but this has not stopped the wanking.
