Jonathan,

This sounds like the most awesomested idea for a dojo evar. :-)

And yes, I agree with you in your original post that a vacuum is a bad
thing. Like anything worth doing I suppose it's a balancing act so
people don't feel coerced into methodology X while being exposed to it
in such a way that they take away the stuff that inspires / works for
them.

Any / all suggestions for how to walk this tightrope are most welcome! :-)
