comparing OSS licenses

[Aidan Gauland]

Hello,

Someone's probably going to tell me that they got an answer to this from their 
first Google search (but I have tried looking for this already), but here goes 
anyway...

I know that there are a whole bunch of GPL compatable open source licenses out 
there -- the Apache licence, the X11 license, the BSD licenses, the MIT 
license, the Mozilla licenses(s) -- but what the heck are the nitty gritty 
legal differences between them?!  The GPL seems to be by far the most popular, 
but that's all I been able find out, and I don't understand the 
lawyer-readable legal code well enough to puzzle out all the differences 
between the licenses for myself.

Has anyone already done this?  I tried the Open Source Initiative's site, but 
that didn't have a side-by-side comparison of any licenses.

Thanks,
Aidan
