\[Last update: 2025-01-05\]

The Bay Area rationalist community has an entry problem! Lots of listed groups are dead, the last centralized index disappeared, communication moved to private discord and slacks. This is bad, so we're making a new index, hopefully up to date and as complete as we can!

This is now being mirrored at [BayRationality.com](http://www.bayrationality.com/), which will hopefully get prettier formatting over time.
