Does anyone out there remember PlaNetwork? It was a fabulously geeky conference that had a good run back a few years ago now. I loved its combination of high geekery and values-based idealism. I remember meeting someone through pre-event communications that I collaborated with to build a beautiful altar/centerpiece in the middle of the conference room, and dancing afterwards to music I'd never heard before under a projected screen of Electric Sheep images. It was that kind of "happening". Definitely a bit "hippie" and not slick by any means, but deeply sophisticated on many levels, not least technologically, and extremely satsifying.
There's another event that has sprung up in the San Francisco bay area in the last couple of years called Wisdom 2.0, and I've been watching it with great anticipation.
