I'd like to add that there are some other, proxy measures, that people can use to evaluate how busy a grid is:
* Activity on its forums
* Its event schedule
* Activity on social media
* Activity on grid-related blogs
* Third party surveys (hint: vote now!)
By all these measures, InWorldz is doing extremely well.
If we had a grid that advertised a lot of users, but had no in-world activity, events, blogs, social media mentions, etc.. then I'd be very, very suspicious. (And I'm not going to name names, but I've seen this happen, and have dropped those grids' stats from my reports.)
