I didn't look at all his threads. I opened ones where the topic seemed interesting. One on SCO Linux comes to mind, and a few others. Of those, most of the new posts were on topic or pretty close. Of the others - given that Doc presumably wanted to post whatever it was somewhere, would you have preferred a new thread to adding to an old one? (Remember, that's what this thread is about, not Doc's posts in general.)
If you have a problem with Doc's posting as much as he does, or the topics he posts on, say so - but let's keep this thread on topic! Otherwise, it becomes an example of exactly what its originating post complained about.
