Sure!  I think our conventions are pretty typical for the ruby community, but a couple things I can think of:

* The `private` indentation thing we talked about here.
* We don't use seattle style for method defs, e.g. `def foo(a, b)` rather than `def foo a, b`.

I'm blanking on other stuff but I'm sure there's more.

It would be nice if common config for this could go in `rspec-support` so we don't have to maintain the same set of config across multiple repos.

BTW, I've been thinking of looking into integrating yardstick as well, which I see that you use.  For RSpec 3 I would like 100% of our public APIs documented and everything that's not public documented as not being public.  It seems like a good tool to help with that.  Seeing as you have the latest commit on that repo, it looks like you have experience there, so if you want to help get that set up for us that would be superb :).
