people mismanage their time in various ways. I doubt he's 100% efficient with his time. The people who post on CB come from a diverse set of backgrounds, many of whom are very successful in their lives. I don't think you can broad brush the entirety of the board without being wrong on some level.
If he doesn't like CB and doesn't respect the posters, then don't post here and he certainly shouldn't care what we have to say about him. It seems like he's trying to diminish CBers, because opinions were stated about him that he doesn't like. If he wants to be effective, he should correct the record and move on. Attacking all the posters to a message board even the ones who have never stated an opinion about his services (nearly the entire board), shows poor judgement on his part.
