If not, don't bother, since it's a pretty silly affair. Even though the Volokh bloggers have been begging their readers (of whom, based on their site counter, there must be 20,000+ per day) to vote almost every day for the last week, they are still trailing David Lat's gossip blog, Above the Law, and have mustered only about 4,000 votes (and bear in mind you can vote once every day!). But, really, who cares? For intellectual content, Balkinization is pretty obviously the best of the law blogs listed, and remarkably, some equally substantial blogs with law-related content aren't even in contention as a choice (Becker-Posner most obviously).
UPDATE: Mr. Lat seems to have the matter in perspective!
