Tweetbacks - Trackbacks from Twitter

@danzarrella, a self-proclaimed viral and social marketing scientist, created a new Wordpress plugin called Tweetbacks. Tweetbacks acts in the same way as a traditional trackback, but just displays the Tweets about a specific blog post. The code is pretty lightweight and easy to install (one line of JavaScript). You can see Tweetbacks in action on his site. Dan has some other cool free tools on his blog, so definitely go there and poke around.
