Tweetree puts your Twitter stream in a tree so you can see the posts people are replying to in context. It also pulls in lots of external content like twitpic photos, youtube videos and more, so that you can see them right in your stream without having to click through every link your friends post.
Social Profiles is a Wordpress plugin which lets you add links to your commenters' social profiles. The links can be text links or graphical ones, but only registered users of your Wordpress site can input these, thus allowing these profiles to show in their comments on your blog posts.12 different social networks are included - Twitter, Digg, Delicious, StumbleUpon, being some.
"Now you can personalize your Twitter background like never before. The tool below will help you create free Twitter backgrounds that have the same look and feel as those done by professional graphic designers."
