I've been enjoying SF0 a lot. It's a neat idea with a great community. I've already met a handful of people in my area (Washington, DC) and done some really fun tasks with them. That said, identifying local people is a little difficult other than using the Distance sort in the Players screen. That still requires people to accurately list their ZIP code, which may not always be the case. I think there should be a way for higher level players (6 or so?) to create a user group that's not affiliated with the SF0 group. They're completely voluntary, but can make it easier to organize events for people outside the Bay Area, which the game is getting a greater and greater number of. It can also foster some additional competition between the user groups, if in an unofficial way.
