feeding tweets to the text-hungry

There's a whole heap of things that feed on short snippets of somehow-interesting text: fortune cookies, teabag tags, bumper stickers, Threadless T's, Better Place's 10-word minifestos, etc. Meanwhile, Twitter relentlessly spits out snippets that are 140 characters or less. (Not that all tweets are interesting, but some of them are designated as favorites.) So why not feed the latter to the former, i.e. use somehow-interesting tweets as fortune cookies, etc.? Create a feed of just favorite tweets, and you'll have a bunch of awesome slogans for Threadless T's.
