If you've used a file-sharing service that lets you upload files and send the link to a friend via email, you might appreciate FileTwt. It's the same idea, but you pass the link along via a tweet or a direct message on Twitter.

In keeping with Twitter's spirit of brevity -- or maybe with FileTwt's inevitable bandwidth costs -- the max file upload is currently only 20mb. FileTwt is a brilliant idea for a couple of reasons, though.

Twitter can be a good broadcast and promotion mechanism, and sometimes you want to share a new design or a demo of some music you recorded with everyone who follows you on Twitter. Or maybe you have a friend who needs a file, and Twitter is the only way you two are connected. Tweeting can definitely be faster than sending email.
