Shouldn't proposals that are heading towards beta have some other way for committees to stay engaged?
A more general question than just adding comments or discussion to proposals that are in the commit phase. This would be most beneficial for proposals that might not have an immediate following but are steadily advancing through the commit phase (I'm basing my idea off the Physics proposal which has 2 or 3 commits a day and will eventually make it to 100%).
I think a Stack Exchange site has a much better chance of survival if committees have a way to contribute and stick around between definition and beta. What ideas do we have to keep people around?
