Ask HN: Startup events in the Bay Area?

I feel like I've been rather insular recently and need to participate more to the SV/SF community and get to know more folks out there, see what they're working on, and share what I'm doing as well.

How does one find out about all the good events in the area? I'm already on the StartupDigest list, but I'm wondering if I'm missing out on something really good.

Thank you!
