Don't believe the drivel spouted by that particular schizophrenic detractor, Alex. It's very obviously colored by a highly negative bias that is NEVER to be trusted (as history hereabouts has already revealed countless times).
#2 is actually attributable to Len Wein (JB has credited Mr. Wein for such in the past).
Simply put (and this is my own take), don't bring the fan "mentality" into writing for the big 2. A lot of people have tried to steer this subject towards independent works, but the MAIN thrust is towards Marvel & DC superhero stories...IMO. JB points out
one of the worst cases is the JLA/Avengers crossover. No complaints regarding the artwork by George Perez, of course.
And (in response to MightyQuin) I don't see anything elitist in JB's view in regards to fans turned pro. What's next? JB's jealous, too? Blech!
