I'm there now.
Count is just under 200.
Where is everyone?
Alas, it seems it was not nerds who put the map there. So it only counted those who were there exactly at the time. Meaning if you was there for 10 seconds and then went elsewhere, you only showed in the stat for 10 seconds. They probably should have asked for others' advice before doing that. Am sorry to have put the link here.
Possibly they figure out how to ask for the real statistics from the site. The map did not show me at all, at least.
