You may have seen this already, but here's another short blurb from me: Brian Dorsey, a familiar face to those of you who have been at the last 2 or 3 PyCon conferences, has launched a Django-based Web site he called Noonhat. The tagline says it all: "Have a great lunch conversation". It's a simple but original, fun and hopefully viral idea: you specify your location on a map, then you indicate your availability for lunch, and Noonhat puts you in touch with other users who have signed up and are up for lunch in your area at that time.
This has potential not only for single people trying to find a date, but also for anybody who's unafraid of stepping out of their comfort zone and strike interesting conversations over lunch. Brian and his site have already been featured on a variety of blogs and even in mainstream media around Seattle. Check out the Noonhat blog for more details.
Well done, Brian, and may your site prosper (of course, the ultimate in prosperity is being bought by Google :-)
