+1haha, for a starter distro to install and go; Ubuntu is fantastic. For a distro to learn linux on it's horrific, the amount of vanilla code and linux standards are well.... non existant, which makes it possiby one of the worst distros for learning.
I'd vote fedora as a good learning distro.
, Gentoo is lovely to use (but understandable comment) - one of the more difficult to install but has always been incredibly easy to maintain in comparison to some of the other distro's I've used 
(just dont do a Gentoo p2 as no one thought that was cool when I showed off its ability to do sound and scummvm!)
