Greg,
I've known Keith from SI for a couple of years. We've posted on a couple of boards together. I see him as sincere and honest. He's my friend.
I'm uncomfortable answering questions about my relationship with Vendit or anyone else with whom I've butted heads, as I feel we all must make those judgements for ourselves.
I'm a trained therapist too and I think your point about the psychopathology on the internet is very valid. I'm hoping that as the market stabilizes, the posts on market-related sites such as this will again become friendly and helpful, as originally intended.
