It was my understanding that Main is intended for polished final products, and that drafts, polls, and, well, discussions, belong to Discussion. And for me a "nexus of co-working efforts" is a discussion. Its main value is in the discussion process rather than in the article. To put it in another way, most posts in Main (with the notable exception of meetup announcements) will not lose much of their value with time, while this post will be of very little value once people stop regularly coming here to coordinate social productivity experiments.
I like this post, but I think that it should be in Discussion. If you agree with the latter sufficiently to be bothered, add a subcomment to that effect.
