Yeah I am kinda disapointed because there doesnt seem to be many outside the US using these sorts of sites.
Well, that is because there sites should be multilingual.
However, currently I want to do some bigger improvements to localbitcoins.com - I want to improve the overall concept. After this bigger development, I will start also translating the site to multiple languages.
I'm actually very excited if someone manages to solve this "local" bitcoin exchange problem - it would make it much easier to travel with bitcoins, for example.
Perhaps a mobile app utilising one of the other location based apps like foursquare,gowalla,SimpleGEO etc.
People can then "check in" and add their location. For instance you might be at the airport for the next few hours and in that time someone could meet you. Not only is this location based it is also TIME based.
