Until now, the only way to mix your microblog and Creative Commons licenses was to sign up for the free-as-in-speech service identi.ca (or run your own instance of Laconica), which requires all posts to be under our Attribution license. But as of February 18th, thanks to the work of UK author Andy Clarke, you can CC license your twitter feed via TweetCC.
The idea is to post a tweet to Twitter letting @tweetCC know that what license (or waiver, in the case of CC Zero) you want your feed to be under, and then the service keeps track of your choice for the rest of the web’s reference. Users can also look up whether and how a given Twitter user has chosen to license their feed. Right now, our Public Domain Dedication is the default and thereby most popular choice, but take a look at the rest of our licenses offered on the site, and CC license your twitter feed today!
