I (too?) am nostalgic for the good ol' days of Usenet. I'm very very unconvinced that an NNTP-based system could realistically replace Less Wrong. I'm interested in what you have to say, but wonder whether there's value in some kind of brief overview post along the lines of "Here's the one-paragraph summary of why I think this is probably a good idea. Here are one-sentence summaries of the strongest five objections and why they don't change my mind."

(But maybe not; the effect might be to put off people who could have been persuaded with a gentler run-up.)

I do wonder whether you can really need twenty posts to make your case. Perhaps much of the material will be useful in other ways (e.g., to inform future attempts at community-building, collaboration, etc.)?
