Jonathan Nelson ( http://news.ycombinator.com/user?id=iamelgringo ) also puts on a http://www.hackersandfounders.com event every few weeks that's good and get HN folks.
But if the event does go down, I'd be willing to show up.
Recently I've been making an effort to talk to more people (offline and real conversation) instead of being holed up in the CS lab coding all the time and its amazing how positive of an effect its having on my mood and creativity =)
In fact there is a New Tech Meetup every first Tuesday of the month near DLA Piper, Palo Alto. They have about 3-4 demos by hackers/founders followed by networking. I have easily seen 150+- people.
I should note that I met my 2 cofounders at SHDH. Hackers aren't the only attendees.
