Hi there, and welcome to LQ...
I'd suggest reading Stallman's essays on
Open Source, they are available in print,
and I'm quite certain that googling will
point you to on-line version, too.
http://www.stallman.org/
Then there's Eric Raymond's homepage
which has a host of information and relevant
links...

My motivation to be here and help people
with linux is that I can't stand MS :} and never
could, since the days of MS-DOS 3. Their
products, the "ideals" behind their marketing
and their service make me want to throw up. :)
I don't think that linux in it's current manifestation
is the best possible product, but I sure as hell
know that it's the best thing available, and it's
free, which is a major bonus :} and makes it
worthwhile to support it.
Cheers,
Tink
