I should have guessed it, as popular as twitter is among bloggers (for good reason), several wordpress twitter plugin have been built.
The first one I tried was Tweetbacks. The first time I used it I had a few thousand twitter spam/error comments added to my comment section. That was not going to work for me. I saw others where having the same problem and was about to uninstall the plugin, but two cool things happened. I could use TweetBacks clean up tool to get all the tweeter comments out of my database. And the plugin was upgraded. When I activated it with the newer version, my problems were gone.

Or if you prefer, also check the box for Automatically insert a small link at the end of posts instead of a large icon at the top-right and it will look like this:
WP Twitip ID
WP Twitip ID adds a twitter id field to the comment form and when your readers comment, if they add their twitter ID a Follow Me link is added to their twitter account. This plugin was harder to use as it requires editing the theme’s comment.php file. Be sure and watch the video on the page for help in this.
