[T]here certainly _is_ a policy that facilitates whatever communities may not have been fully represented in the body of talks: Those are the BoFs.
Lori, I would argue that those don't make up for the main body of presentations being inundated with talks that focus only on one community--not having a policy of exclusion doesn't necessarily mean that exclusion is not happening de facto. I don't expect you all to solve this problem, but I think (and maybe you can agree) that it is worth discussing. Also, I'd suggest reading the other messages in this thread, I came much closer to properly stating my intentions there.
