If there were a tag called "defined-list" or something similar, I would have chosen that tag. Recommendation was the only tag that was remotely close. If the group ends up believing this is a good type of question to have, then I would suggest adopting a "defined-list" or something similar to that to imply the well defined and (close to) objective nature of the question. – Joe Golton Jun 14 '12 at 16:31
