Closeby - A store locator map for your brand

I get that you're trying to make store locators easier, but I'm worried this might oversimplify things too much, how does this perform when a site has hundreds of locations, also what about the privacy concerns with location services, would be cool if you had some kind of demo with higher volume locations to see how it handles under stress, could also consider an option for advanced customizations for those who do have some coding knowledge,
