This document discusses location-aware apps and hacking together location services. It begins by asking common questions like "Where?" and "What's around?". It then covers determining a user's current location by asking the user, sniffing the IP address, or inferring location from data. Methods discussed include using the W3C geolocation API, MaxMind IP lookup, geocoding, reverse geocoding, and Yahoo! GeoPlanet. The document points to code demos and resources for building augmented reality and mapping apps using location services.
