Google+ is all the rage. Twitter is still rolling along. (Although Tweetdeck is just a steaming pile of Fail Whale since Twitter bought it.) Facebook is still booking faces. And of course the thing that drives them all (or supposedly will) is advertising.
Each of the social networks has a "Like" button or a +1, or a retweet, or something for others to follow along. But you know what these services and websites, and blogs, and headlines really need? A Stupid button, or some form of a Total Rejection Button. I know folks have talked about "disklike" buttons before, but when it comes to Ads and how that scam actually works on websites and social services, etc... I think we need to start measuring just how stupid some of these things are.
