Hey! Thanks for your feedback.
You're right, it is a bit of a chicken and an egg issue. One way of combating it was to make automated posts in preset areas based on target demographic and population rates. Outside of that, I believe for an app that requires people in a certain area to adopt in order to generate activity, it becomes more difficult to gain popularity all around.
It doesn't work for me either. I'm on Firefox.
That website's markup is incorrect. There are also no <html>, <head>, or <body> tags in that webpage either, which might be a good explanation of why.
