I used to read punaji a lot, but the character of that board really didn't sit well with me for various reasons.
David always struck me as a little bit in love with himself and his work, but that's just an opinion. The fact that he seldom listens to critique doesn't render it invalid, and the fact that he hasn't improved much in the last few years....well, I hope that he is satisfied with his current skill level.
Of course, he's never stuck me as a bad guy, and I don't see why anyone would dismantle a forum.
