1. You can think of us as S3 for location data. Before S3 scaling file storage was a messy, complex, and costly proposition. After S3 it was as simple as posting files to an endpoint. We do this for geometric/location data. We store and index your data and allow you to easily do geospatial queries against your location data.
2. We give away 1m calls a month, which is the same that Twitter gives away for free, and more than Google Maps does. The pricing plans are based on what it'd cost to manage your own infrastructure. We'll be adding lots more features, options, data, etc. in the coming weeks/months.
3. To the people saying they can just install GeoDjango and PostGIS, I have a few questions. How much time are you spending building and maintaining your own location API? How much does it cost to rent/buy that hardware? Is your location infrastructure multi-homed in three data centers? Does your location infrastructure come with premium content like global weather data and 16m+ business listings? Can it keep up with the real-time geohose from Twitter? Does it do URL callbacks and S3 backups automatically? We handle all of that for you.
4. The location marketplace will allow developers to tap into billions of points of interest and previously unattainable features for low monthly costs. For instance, Metacarta and Quova solutions are very much enterprise solutions that cost real money, but they'll be available on demand for small per-drink/per-month costs. We've indexed over half a terabyte of location data (when you're talking about point data that's a lot) that's instantly available to developers.
5. We have robust SDKs for the iPhone, including an augmented reality view. The AR view allows you to show a sophisticated AR view of your data, in our API, in about ~10 lines of code.
You all are absolutely right that we need to do better at messaging and whatnot. We're working on that. All I ask is you give us a chance and don't dismiss what we're doing as "just GeoDjango."
