I didn't say anything about Archlinux being used by most people - your comment is completely irrelevant to the topic at hand... but Archlinux is fairly popular, it's in the top 10 most popular distros out there - and is more popular than the vast majority of Ubuntu derivatives.. but yeah, Archlinux is geared at a more technical minded crowd... I commented that i use Arch, that is it.
New Linux users who install any distribution find out very quickly there are many DEs to choose from. Again, stop claiming you speak for the majority - you only speak for yourself. You're not psychic - so shut up with this "I can read the minds of the majority, i know what everybody uses on the PC, how they have set it up, their habits, etc. ~ You don't know ANY of these things.
