This is a non-profit event that spun-off from Andrew Gwozdziewycz's Hack and Tell in NY. It's been going strong for three months and has already seen some really great presentations.
If you're in the area, I hope you'll stop by!
How many people have been at the last few?
First one had ~40 (disclaimer: I advertised free food). Second one had 23 (with no food).
