Link: Checkmates: a mobile friend finder prototype for eTech -- Chad Dickerson’s blog.
Check out Checkmates a Yahoo! Hack by some great, cool folks... Karon Weber, Jonathan Trevor, Ed Ho, and Sam Tripodi. I saw them here last night hacking away.
This is a cool mobile app that allows you to announce where you are to your friends with a map visualization. Very nice.
Take a look.
