I liked the guy's insight too, and told him as much.
But he rips anyone's head off if they don't salute his posts as gospel, which is a red flag. And gets very personal when he does it. He also got a little stalker on me, which is another red flag.
I suspect that if he is really gone, it has more to do with some serious issues he has in interpreting ratings data in the "ACC" thread. He has gotten "Ratings" and "Share", and "TV Sets" and "Total Viewers" completely confused. And he did it twice, once after I had pointed out his mistake. Even an interested lay-person in TV marketing should know the difference between the three. If he is the expert he claims to be, he should know this stuff cold. This is the equivalent of a CPA confusing revenue and net income or an equity trader confusing bid and ask. It just doesn't happen.
