Over at Leiter Reports, you may vote for the best philosopher of the 20th century, as well as, while you're at it, the best philosopher of the 19th century. However, due to the threat of contamination by the unwashed masses, "non-philosophy blogs" are urged not to link to these polls. So if you think this is one of those, you better not go over there. You have been warned. (Also, re: the first poll, see the (*cough*) lively discussion here.)
UPDATE [3/4]: The madness continues with a runoff pitting the 19th and 20th centuries in a head-to-head battle.
However, everyone is welcome at the Philosophers' Carnival!
