Good index, stales; thank you for posting your ideas. I don't have time to read everything, much less to post as much as I'd like, so I'm gonna try your method. I agree with you that the greater diversity of posters, the better, though by your index, as you said, we still run the risk of one or two posters monopolizing one (or many, as has been the case lately) thread.

As to your converse, yeah, under 10% is a pretty good index of specialization. Then we check the thread subject, and hope for the best.

Thanks again.
