Are Gentoo users really that large a group of people?

In numbers, I mean, not form factor.

No, specifically gentoo users can. The distro literally serves no real purpose, nobody with any unix experience would consider using it. It is quite literally the distro for people who don't know what they are doing, but want to feel "advanced" by watching stuff they don't understand scroll by.

Your comments tell me more about you than they do Gentoo users.
