So we can't have the secret society anymore because this place is now full of retarded /g/ros, our culture is now dead. You can go to the fields and commit seppuku there. Sayonara.
Seriously though, I haven't counted. I can't be bothered. From a quick glance in the admin panel, there's maybe 20-50 different individuals posting within a 6 hour timeframe? The range depends heavily on the time.
I'm sure the amount who browse is easily 10 times that, but I don't keep HTTP logs so I wouldn't be able to check.
