Speaking off-the-hook as a normal nerd, I like this angle. There's actually plenty of Google stuff I might be interested in, but their size and my privacy concerns, partly about Google, keeps me off.

Cultivate your trustworthiness as Andrenid says and you will probably have at least my business and quite some more. Explore (even more?) just what keeps people from sharing their location - their privacy concerns and how they, and you, can get around it in a way that is useful to them. That said, I'll check out your app.

I also really liked someone's suggestion up-thread to animate your app and make it a good place to hang out. That sounds like an app I could and would use. Best.

Second this idea - privacy may be the big new selling point of future services. Trust a bigco or trust us? Public is free, but private is extra (private groups, private social circles, private sharing of specific data).
