Hey-o,
I recently built http://drinkkit.com/, since I wanted to dig into some geolocation crap for a side project, and I wanted a way for people (in this case, Redditors) to find one another at the Stewart/Colbert rallies in DC this weekend without the background noise that Foursquare/Gowalla would introduce.
At any rate, I open sourced it, because while I don't think it's anything too special, I did find myself wishing I could've found a small scale project (like this) to easily glean tidbits from when it came to the geo-stuff.

Dunno if anybody here is/would be interested, but figured submitting it certainly couldn't hurt. ;)
