Hi Holmes,
Thanks for making this thread! First I want to say I’m glad you’re on the MGRC!
I actually disagree with this. 
I think that there is an inherent tension in having a diverse MGRC that can represent the wants/needs of all Zcashers, and having a MGRC that is small enough that it can be agile and effective, especially when things are being set up. Just being aware of some of the biases of having a committee of mostly men based in the US is already a great first step. (edit: looking now at Zooko’s comment there are some process ideas like running together on a ‘ticket’ that could have helped)
The reason I made my comment was that I looked at the list top choices for MGRC, and saw that the next 4 were very good candidates who would have added important perspectives. 2 of them are women. 2 of them are based in Asia. One of them works at ECC and would have been a valuable coordinator with insight in ECC perspectives. I don’t think that we should have any sort of quotas for diversity or anything like that; all of the these 4 people had tremendous qualifications apart from these factors.
