sitting at noisebridge right now: https://www.noisebridge.net/wiki/Noisebridge this is almost what i had in mind, only my version has bedrooms, showers, and allows pets. noisebridge kicks ass. it's a giant hacker studio. i've never been here before. if you're a hacker and live in san francisco, you owe it to yourself to just show up here at least once. i will be here for awhile tonight if anybody wants to chill out.
Unrelated: there's also another movement called "cohousing" which tries to strike a middle ground between the post-WWII standard of one-family-per-house, and communes that tend to have a complete lack of privacy.
