I reckon most motorists find vanity plates distasteful. Upon seeing a plate bearing the letters 'Ph.D.' or 'M.D.' or 'J.D.,' the response is likely to be: BFD! In any case, who needs vanity plates when one can have for free one's very own vanity blog? And weblogs have this advantage: they are not in people's faces. You must freely decide to visit a site, and if you don't like what you find there, you bear at least half of the blame.
