TweetCC - Twitter & Creative Commons for Tweet Licensing

It appears fellow Tweeters are going to have to give due props before retweeting from now on. This morning, an interesting occurrence came into being...TweetCC. Over at TweetCC.com, Creative Commons has applied a form of intellectual property, although not really, on Tweets leaving them "licensed." TweetCC (@tweetcc), designed by Andy Clarke (@malarkey) and Brian Suda (@briansuda) and developed by Brian Suda offers to:

tweetCC makes it easy for you to offer your tweets under a Creative Commons Public Domain Dedication or other Creative Commons licenses. Anyone wanting to reproduce tweets can then do so without asking you. Unlike some Twitter-based services, we don't ask for your Twitter login or password. We would even go as far as saying that this password anti-pattern practice teaches people how to be phished. Don't scatter your passwords around like chicken feed.
