Thank you for your input. The problem with all the CC licenses is that they aren't designed for scripts and software, so they don't take into account concept like source code. I was more thinking of GPL, LGPL, MIT, Apache, BSD, WTFPL, etc...
For what it's worth: currently I use the BSD license, but with an added restriction that derivatives cannot @include Facebook (due to abuse on uso).
Userscript license choice
So I want to 'protect' my userscripts with a license. But there are so many with little differences.
I was wondering what license you have chosen and why...
