I really appreciate you putting so much work into this. It is very important, and I believe could do much to increase awareness of and participation in these processes.
I've left most of my thoughts as line comments on the proposal document, but since discussion of platform choice is taking place here, I'll quote the Motivations section:
- Higher than necessary barrier-to-entry.
For the purposes of this proposal, whether we would prefer a competing alternative is secondary to the fact that a Github account has become a very low common denominator for people wishing to participate in the development of open source projects. If we decide to proceed with a non-Github platform, we need to make a compelling case that the alternate choice does not raise the barrier to entry, or else we need to decide that we have different priorities for this effort.
Thanks,
Adam
