I'm rather skeptical of the "rationality dojo" concept because regular dojos are far from a reliable training method.

The parts of the dojo model that I'm thinking of importing are:

1. Regular periodic meetings of a few hours, probably weekly or monthly.
2. A geographically local userbase.
3. Clear skill gradations and demarcations and test-based advancement.
4. Regular open training periods.

Basically, this seems to manifest as a skill-focused meetup with a bit more structure than normal, and possibly more cash transfers / dues than normal. Do you have warnings about those features, suggestions of other features I should think about importing, or other comments?
