I think there are a lot of great names up there (particularly IrrX, lackofabetteridea, Unbiased Observer, and sheltron, who have exhibited a lot of careful thought about how the board would work best -- but really everyone listed is a great candidate). I do, however, understand people's concerns that the new mod or mods not be associated strongly with any of the board's "cliques." I have a few additional names to throw into the mix (because they are unfailingly pleasant and generally straight-shooting types), but I don't know if they are at all interested, visit the site enough, etc.:
non parata est
I would also like to nominate Elephant Lee, though I believe he has already said that he doesn't want to do it, alas.
