>Promising to make you look wired and magically promote your content in social networks, the Like, Retweet, and +1 buttons occupy a good spot on pretty much every page of the World Wide Web. Because of this, almost every major site and world brand is providing free advertising for Twitter and Facebook. But do these buttons work?

When I had the Twitter buttons on this site I can tell you that they did very little. More importantly with tweeting features being baked into Apple’s Safari browser, these buttons are going to mean even less.

Don’t bother putting them on your site — I wish I hadn’t.
