Leave virtual notes around your neighborhood with BlockChalk

With all the location-based services sprouting up, it's surprising to find one that's a little different from the now-formulaic location-based game. However BlockChalk is just that. Instead of requiring you sign up and tell your friends where you're re-enacting The Hangover, BlockChalk lets you anonymously leave messages for your neighbourhood to read. If you're wondering how on earth this would be useful, the BlockChalk folks provide this handy guide:

• Got something to say? BlockChalk.
• Neighborhood tip? BlockChalk.
• Lost kitty? BlockChalk.
• Lost croc? Call 911.
• Borrow a lawnmower? BlockChalk.
• Report a pothole? BlockChalk.
• Sell your pot? NOT BlockChalk.
• Pub crawl? Absolut BlockChalk.
• Bitch about BlockChalk? We can take it.

In short, it's a ridiculously simple local noticeboard for nearby folks, with options to share "Chalks", reply publicly and privately, and bury useless ones. There's an iPhone app and webOS app out now for the service: with support for other devices in the works. Whilst it's not currently the prettiest service out there, it's certainly fun -- and potentially very handy to know what's going on around you. Check out our gallery, and an introductory video after the jump!
