One suggestion though, the fact that use cases are wide open could stifle growth. I'd suggest a few different landing pages you could A/B test, each covering a very specific use case.
You could have one page explain that you can save your parking spot and share it with others. Another for sharing a meetup location. Another for saving your favorite locations. Yet another (where you may win big) would be easy location saving for photo and film location scouting.
I'm very interested in location and really trying to figure out what GeoGraph can do to deliver the most usefulness to its users
Yes, I want to have a simple, powerful tagging interface for providing more context.
Getting data out via JSON is easy, just have to build a secure API endpoint.
Like imgur for location. No sign up & 1 click to share your current location. If you sign up, you can save your location privately (only you can see it).
Use cases are wide open. Save your parking spot. Share location to meetup with a friend. Save a special spot in a forest. Etc.
If you use check-in services, GeoGraph may interest you. If you never share your location online, you shouldn’t use this.
Working on new features to make location more useful.
