Live/Realtime chat is a definite possibility.
Tools like hangouts/slack are the next generation of social interactions and I am already in a few groups based around those systems. The trick is finding the right interface to make it work. (the two mentioned seem to work okay)
This article is something that has been in my head for a while. I hadn't planned on doing a write-up so soon. I wanted to take the time to a) refine my ideas and b) figure out how to express them clearly before posting. But the recent post Less Wrong lacks direction made me change my mind. My thinking now is that I overestimated the downside (wasting peoples time with a less than fully thought out post) and that there's enough value to justify posting a rough draft now.
LessWrong has been one of the most amazing things I've experienced in my life.
