Well, the one I'm currently in is pretty small, and has some people I was friendly with when we were all still in NE. The fact that it's small makes me feel much more comfortable (and makes me feel good when I'm talking rather than something like main where I just make snyde remarks where I can) than guilds where it's filled to the brim with unused alts and autovendors, where everyone is SRS about stuff like woe and pvp.
