As you may know, my favorite desktop client is Tweetie for Mac. If you use Twitter through a desktop client (whether it’s Tweetie or some other), you probably wish you could click those green retweet buttons and have them open in your client instead of taking you to Twitter.com.
Now you can, at least, if you use Tweetie for Mac.
I whipped-up a quick Greasemonkey script, known as Tweetie Retweet URL Replacer, that rewrites any Tweetmeme button you come across to load the retweet into Tweetie.
This works on the same principle as the bookmarklet that Atebits supplies on the Tweetie website.
At the present, the userscript only works with Tweetmeme buttons, but I may expand it to include other popular widgets in the future.
