Thanks for the comments everyone.

But instead of having everyone else scroll past this o(n^2) collection of quote pyraminds (from original post, through each reply) to get through the thread, we could have an O(n) discussion in the wiki Discussion page instead.
I've moved the convo over and added my reply:
http://wiki.nxtcrypto.org/wiki/Talk:List_of_Proposals . See how much cleaner this is than ever-growing quote pyramids? Take a look at
this and
this for some idea of how a longer convo can look like and be managed.
Wikipedians have been used to (semi-)decentralized organization and article editing for years now. We could borrow the methods they use.
We can use this main thread to link to discussions we've started. The wiki has a Watchlist feature (similar to forum watchlists) to help you keep track of what's been changed (including replies to your own comments). Click the star on a page to add it to your watchlist.
James, and everyone, how does this approach sound? Shall we give it a try?

EDIT:
I didn't create it in response to James' ideas specifically, it was in response to the general mess this thread has become (c.f. the quote pyramid above that you yourself contributed to!). If you check the List of Bounties and Proposal's page history, I created it many days ago. I already had the hub in mind. I've been trying, desperately, for the past week+, to get people to try other communication methods (like
diaspora*). It's exhausting...
