I was looking around one day trying to find a simple plugin that could take any mention of a twitter username (eg. @tquizzle ) and link it to that user’s Twitter account page. The idea was simple, yet I couldn’t find what I was looking for.
Everything I found was for either comments only, or simply didn’t accomplish what I wanted. So I sat down, dissected Matt Freedman’s Twitter Links to see how he did this with comments, bounced the idea off of @justinshattuck and @tshaiebly, and then added a little more functionality as far as being able to do the same with post and page content as well as comments. So its a trifecta!
You can jump on over to the Plugin page to see more about it.

Great work Travis! I foresee this being a very useful plugin for many people.
Thanks! I hope it proves useful for many blogs.
