I did something today I should have done a while back: relicensed all my blog and website content under CC-BY-SA. It previously included a noncommercial clause, but after reading a discussion that included a link to "The Case for Free Use: Reasons Not to Use a Creative Commons -NC License" (I believe the link came from Rahul - thanks, Rahul!) I went "whoa, I haven't actually thought about this before - crud, this makes my website incompatible with... FIX! FIX!"
