Well, gmail's spam filters are very strong though (even too much if not properly trained).
I think one of the main reasons they are using this technique is that a news like e-mail has more chances of getting through bayesian filters... at least for now (I just got a "Alligator attack savages 3 students on school trip" which was recognized 98% as spam, for example, which is just enough to slip through with my criteria).
