I worked in SF prior to the dotcom bust. Since I was commuting and made a day of when I had to be in the office. I took yoga with Larry Schultz - the yoga teach for the Grateful Dead, he had a studio near 4th and Brannon (I believe, memory foggy). He was great to listen to stories and learn from.

As mentioned in another post, I've been to SF Zen Center events both in practice and adjacent classes.

The tech scene now has become much more narcissistic than it was then. I didn't see the evolution as clearly as I did in Palo Alto while working there and in Mountain View.

I would not couple the tech scene with spiritual practices themselves. Judge the so called practicioners not the practice / practice instructors/organization.
