Yeah. I guess you do need a large enough population of actual users to use it.

I just looked through the London one and most things fit into one of several categories

1. Really overpriced
2. Junk that won't sell on eBay
3. Stuff that appears to be stolen. Laptops and consoles without anything else etc...
4. Scams
5. Spam
6. Work at home and earn £1000 a day!
