Like Quantumgravity, I've been using "Linux" for years, but until just a few
weeks ago I did not understand the difference between "open" and "free"
software (or GNU vs Linux, for that matter). In fact, I'm still not fully
clear about everything; but, I know now that there IS a difference, and I am
doing what I can to learn about and to respect that difference. The first
thing I did was to drop Ubuntu in favor of Trisquel.
As for the moniker, I would like to see an unambiguous term adopted in place
of "free", but unfortunately (like myself until recently), most people won't
get it and we will still have to explain what it really means. Even then I
think most people won't really care.
I've read that the American Revolution was fought and won by a mere 2-5% of
the population (depending on whose doing the estimating). They were fighting
for freedom, too. Yes, I'm just an enthusiastic newb, yet I can't help but
wonder how much explaining THEY had to do.
