Ask HN: Worthwhile hacker events in the Bay Area for March/April 2009?

My business partner and I are in SF from Australia until mid April. We are working on a SaaS style collaborative modelling tool. We've been reading up on events listed on meetup.com, garysguide.org, sdforum.com and googling what we can find. Can anyone recommend any other websites, or particular must see events?

Thanks for the plug, Sean (skmurphy).

I host Hackers and Founders (www.hackersandfounders.com), and we get together every couple of weeks to tip a pint and have a chat about stuff. About half of the people that attend are pretty active on Hacker News.

If March 25 doesn't work for you, drop me a line, I might be able to schedule a meetup for you that works with your schedule. It would be a shame to come to Silicon Valley for a while and not be able to hook up and chat with interesting people. That's really why you're here.

The New Tech Meetup: http://www.meetup.com/svnewtech/ happens fairly often and seems to pretty popular. If you can't get in via RSVP, just crash it. A lot of other people do that and they don't seem to get hassled.
