I disliked LinkedIn at first, but with a *lot* of strategic tuning I now find it OK.

It's good if you want engagement with practitioners.

Have yet to encounter any nazis there, it has that going for it

I want a structure in which authors input seed projects with open code, data and prose ; and a second stage that enables reviewers to make direct contributions within a consensus-building mechanism and receive secondary credits. Goal: maximizing project quality rather than maintaining author control

I'm sorry but that's not identified

I say "morning" to most strangers I pass by at any time of day and night, and even worse I'm starting to think it's OK

Not if it's owned by its users.

Hard disagree. I'm leaving anywhere that platforms Nazis. Paradox of tolerance
