Thanks Steven, blockchalk looks like an interesting alternative to twitter's new geo api < http://apiwiki.twitter.com/Geotagging-API-Best-Practices> although it will be dificult to achieve similar scale.
Have you thought about,a mobile AR version?

Point your iPhone or Android browser to http://blockchalk.com to see the HTML5 mobile web client. There's also a webOS app for Palm Pre/Pixi and an iPhone app on the way (currently in Apple's approval process) which adds a bunch of capabilities. > > There is a very easy API (http://blockchalk.com/developers) that gives you full read and write access to the underlying platform. > > BlockChalk lets you leave messages where you're standing and view messages left by other people in your immediate vicinity or current neighborhood (as calculated from your mobile device's GPS coords). The goal I'm building towards is enabling conversations and transactions between neighbors while retaining control over how much identity and location information is shared at any given time. Right now the system is anonymous (you don't even need to sign up) and it deals less with exact locations and more with regions of proximity, like "this block, "within a few blocks", and "in the Mission District". > > So far the main consumers of our API have been our own native client apps, but we're starting to see outside use and want to amplify it.
