Quite a list. Let's add Dennis Atiyeh and the schmucks at ESB, Champion and Big NASA, and the very entertaining "Pissed off Eddie" who changed names one more time to Aladdins Gold. None of them bother me if they went broke - but the ones that rat holed money and skated on a bad year do bother me. BTW, witf is an F+?
But, I think there was a consistent theme in why these books went teats up. They let their lines get stale and sharp money beat them all.
