Why does enterprise really know how to party. This is something I have been noticing for some time now. If you look at Enterprise Distributions (CentOS, OpenBSD, Suse) the community normally really knows how to get drunk. As soon as you go into bleeding edge (Gentoo, Arch) you start meeting the really nerdy "sad" people. Next time you go to an Open Source social event look for the drunkest guy and probably he is someone related to some sort of enterprise.
P.S I am in no way saying that drunk people are more fun or not nerdy. Getting Nerds drunk is amazing fun (as long as you are not the Nerd of course)
