I'm creating a backend tool for businesses that are using Foursquare, Gowalla (and eventually Facebook Places). The tool is for restaurants, bars, retail stores or any business that would use location based services.
I was thinking something with a thumbtack, but I'm not married to the idea if you can think of something to symbolize location. I'm working with developers and they have designers, but I'm not loving what they're doing. Here is a screenshot of the design, but I need a better logo to bring it together.
