Thanks to everyone that came out! Our first San Francisco Hacker News meetup was a great success. We had 525 people interested in attending and had around 250-300 HNers cycle in and out of the event throughout the evening.
Our next event will be in 1.5 months, as we are now doing these meetups bi-monthly. Thanks again and drop me a line to let me know if you have any recommendations on how I might improve the meetups. Here is a link to my email.
