FiVermont:
I am thinking that categories should be subject to ongoing peer review. Literary Sites, for one, needs an integrity check. The description clearly says it is for locations mentioned in literature ("Find something - a house, diner, bookstore, park, etc. - that's used in a fictional book"). It appears that the birthplace of an author is acceptable as well, though not mentioned as such.
I noticed this as well.
I really hope groundspeak is coming around to the fact that abandonned categories are a real problem for this hobby.
I think your suggestion for periodic peer review is a good one but what happends to all the waymarks and logs if a legacy category fails review?
