We need another communication platform... fb/Twitter/email don't cut it

we have created so many ways of pushing/pulling content from friends/followers, but often these are closed networks - my friends are your friends... we follow the same thing. how do you reach actual communities - like your neighborhood?

we've tried to solve this problem with a website called http://skychalk.com, and we'd love your feedback.

ours is a new spin on sharing - you post something to a location - like fastening a flyer to a tree - and people view information by location.

please give us your thoughts / feedback - do we need to talk to our neighbors? do we already have too many avenues of communication? is there room for another platform?

thanks for reading!
