Hi everyone --
I've been lurking here for a while but now have something relevant to
share and would love your feedback...
I've created a system for proximity-based messaging called
BlockChalk. 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.
I'd love to hear what you guys think and any suggestions or ideas you
might have.
Thanks and enjoy!
Stephen Hood
