I don't read blurbs. I tend to see the same ones repeatedly (like the one on Sir Pterry's books in which the reviewer says "Pratchett's humour is [adjective adjective adjective] and, above all, funny." Humour is funny? My gods, what a revelation!) and only after I've already bought the book. My fault for having a few favoured authors and a collection of weighty Russian tomes that don't, as a rule, feature blurbs.
