Bitexch,
You may be interested to know that Ron explicitly called JR a bottleneck, and not in disapproving terms:
https://bitcointalk.org/index.php?topic=265488.msg3759797#msg3759797.
I saw Ron's post. We all want more J.R. time. I know he is doing what he can to make that happen very soon.
Though I still don't think a Board member has to be online 24/7. We shouldn't be structuring things in a way that Board members have to be online 24/7.
I say this as I'm up at 3:21 a.m. eastern time answering questions on Bitcointalk.org because everyone else is asleep.
