We spent part of Friday evening at <Flex Camp/>, a series of sessions about Flex (development tool), held at the Adobe office in SOMA.
SF and the bay area is teeming with awesome and often free tech resources. Yeah, I know this is probably obvious, given the proximity to Silicon Valley, but I'm still pretty dazzled by it. If you're interested in a particular application/software/technology, chances are you can find a lecture or conference or some sort of learning session, often led by the inventors/innovators of said technology. Or, you'll find you know someone who knows someone who knows the guy who invented the track-wheel on the ipod. Its pretty cool to learn about Flex from the people who spend their days developing it.
I was also amazed at how many people showed up on a Friday evening and stayed through the pizza and beer and beyond the intro session. As I mentioned to J., these events strike me as a potential swinging singles scene, though the demographics are still skewed favorably for the ladies.
