The parameters that need to be tuned are the participation types. I think the strictly technical threads probably have better SNR ratios (number of useful comments/all comments?), and the value of comments in the more generic/generalist comments has dropped. Right now, there is a thread where someone is expounding X, but no one has come in to offer him a good insightful rebuttal. I think PG himself said he has noticed a creep of mid-brow dismissals in the comments. The lack of someone who can provide a high level discussion in the marginal threads, is something I seem to be feeling more strongly. (A thread regarding something like Ortiz, or Aaron would usu. have good representation on the other hand)
