LoudTwitter expired, now in bed with Twittinesis
Apparently loudtwitter is dead and the author hasn't much interest in reincarnating it. I know people have posted some frustrated remarks, but I want to take this moment to say Thank you, Yann Kerhervé for providing this service for free.
Right now I've switched to Twittinesis but I might look at using the open source LoudTwitter code and running it on my own box.
Someone said something about Wordpress having a tool to do this too, but Google is failing me on this one.
