In a world of servers the only Free software is AGPL software
it forces you to release code even if you don't distribute your binaries, but only let others use them remotely.
I.e. if you ran a GPL blog engine, you have to give the code to people you give the program (mostly it's Scripts, so nothing to do - they have the code already)
if your blog is LGPL, you'd have to give the source to any visitor
