I think a much more interesting number is the number of threads per day, which -- apart from the mistakes and the crap -- is a good indication of active participation by different people. It is rare that someone starts more than one post a day, and multiple postings even out. If you look at today -- which is not even a work day -- there are over eighty active threads before 11:00 a.m. EST. We are now getting 200 threads a day quite regularly. A year ago it was 100 (I kept a tally for awhile). Before that it hovered around 50 for a couple of years. There is a doubling time of about a year, which is (a) ecologically interesting; (b) noisy, which explains some of the griping; (c) and great.
