It's actually very difficult to find a venue of this size in the Bay Area, though particularly in San Francisco. I say this as both an ex ticket scalper and an event promoter for a large Bay Area event that is coming up.
By the way, please come to my event (the Singularity Summit!) www.singularitysummit.com Use coupon code HACKERNEWS for a discount on tickets.
Are the talks from previous years available? I could not find any links on the website.
I was disappointed to see "past years" was just a list of speakers in no discernable order, with no idea what they talked about (or when), no recordings, no slide decks, etc.
I got an invite for Work at a Startup at the start of the year, but couldn't go because I live in Australia. To avoid the plane ticket I looked at other ways of getting there, like via cargo plane or cargo ship. It turns out the first one is illegal an the second one is more expensive and takes longer :D
