Here’s a little Twitter app for you while we all wait for some serious list apps: This one is called twibbon, and what it does is overlays a little icon over your twitter avatar to show you support something. First I placed the zend framework one, then I created my own for toonlet, of which I am a rabid fan. Then it tweets it and invites all your followers to place one as well. The little widget keeps track of how many supporters it has. You can also do Twibbons for facebook.
