I've done a little bit of open source work (a few small numerics libraries and the beginning of a small project in PHP) and I always release my stuff under the BSD license. To me, the GPL just doesn't seem 'free' (to reiterate what embeddedradical said earlier). All of the stuff I've written has just been to fill a small hobby and because the only offerings out there were all expensive non-free libraries that I couldn't afford to pay for (not for a hobby, anyway). I seem to remember that the very bottom of the networking stack in Windows was (and may still currently be) based on a BSD sockets implementation. If Microsoft had implemented their own methods from scratch, who's to say that things would be as compatible as they are now? I respect that some authors want recognition (or perhaps a job) as a result of the hard work they put in (for free) on a lot of open source projects. But I think software is much more useful under a license that allows people to do whatever they want with it, commercial or otherwise.
