The record simultaneous online user number here surpassed 4000 this month and the record just got broken for a third time the last 14 days (currently 4,238). If that's the record at any one time then there must be >100,000 different visitors here over the course of any month. It's rather sad that this [unmaintained] forum is still the best place for ball busting there is (IMHO). I surmise two conclusions:

1. Ballbusting (by far the most active forum here) is popular; and,
2. Only ~1 in 10,000 users here actually contribute
