Guess I don't count with Chris....
Good to see David Moriarity now telling us he knows who Jim Engh "friends" are, that they "essentially set him up" and of course, were "pretending for so long that he was something that he really wasn't. " I guess David seer powers don't just apply to the olden days!
That said, I agree with him in that I don't recall Jim getting treated badly here. When he wasn't posting, some of his courses got pegged by a few individuals as overshaped and over drained (if such a thing can be true) by using pictures that showed nary a catch basin in the photo, but nonetheless were held up as examples of bad catch basin useage.
And, I remember that one because I got tainted in the same thread!
Back to the original question - its because they are saner than I am. Really, people in this business have no reason at all to post here. Period. Those who do, like me, simply happen to like the medium, much like everyone else who posts here.
