Ok so i'm fairly new to linux. I've only been at it for about 2 years with the VERY user friendly Kubuntu. I am alright with the terminal, I understand what most commands mean, not always the -x's. But To be good with linux do I actually have to be enthuastic about it or is it like windows where over time i'll just eventually figure it all out? I don't even use windows for anything other than playing games.

And also, how many people here use linux as their main OS?
