we'll all (except for those of us that have been banned, incarcerated or donated a pair of concrete shoes) be able to see exactly how many of those 70-something thousand members are active..?
This information is freely available on the site, just go to the
member list, which may be sorted by number of posts.
Coincidentally, I recently did take a closer look :
29402 members have made at least 1 post
top 10000 : 11 posts or more
top 5000 : 30 posts or more
top 1000 : 167 posts or more
