Creative Commons

This is the most intelligent thing I've seen in ages on copyright. One of those things which is so simple you wonder why nobodies done it before... The Creative Commons (CC) alternative to Copyright. See their fantastic multimedia presentation here or visit their main website.

This is a very nice extension of some copyleft ideas and as soon as I get round to publishing my revision notes I'll be putting some kind of cc copyright on them. These things only work if you use them.
