Ask Slashdot: Comparing Open Source Licenses

El-ahrairah asks: "I've been working on several projects over the course of the last few years, each of which have reached the stage where we are planning their release to the public under Open Source licenses. I have done quite a bit of research into various OS models, but I am nevertheless no legal scholar. what I am wondering is this: what are the pros and cons of various licenses, are any YAOSL (yet another Open Source licence) models valuable, does a line by line comparison of longstanding and new licenses exist?"
