If you're one of the readers who finds De Novo through a search like "what law schools will accept me," I recommend reading Alex Wellen's writings in today's New York Times. The first shreds the US News and World Report rankings; the second tells you where to get more reliable information. (Including stuff I didn't know, like the sudden decline in the number of teaching faculty at my own school from fall to spring. Eep.)
UPDATE: For readers disappointed by dead (or at least severely injured) links, the ones in this post now work even without buying the article.
