This thread is talking about 2 different sites with very similar initials.
BoK=Blood of Kittens. Quite often full of crap but always has something interesting to say(whether based in reality or not) in order to keep site traffic up. He is a spinmaster and agitator who always thumps his chest when he gets something right but conveniently forgets about all the things he gets wrong.
BoW=Beasts of War. Quite often right on the money and rarely says anything they're not pretty positive about. Seem to have some support from inside GW that gets them their scoops shortly before GW can officially announce anything.
