Ed - I can answer one of those. Re moderators:
First of all, they are free, surely, to operate as they please. Mn is unusually light on the moderation, and is famed for being so. It's like telling a tabby cat off for not being black. I don't know the rhetorical term for it, but it's definitely odd.
Secondly, mn historically DID have moderators, it is no longer so obviously the case precisely because it is a big site - they have fancy schmancy software and have achieved that "wikipedia" thing of multiple, swift, self-correction. But you need a (large) critical mass of posters for that.
Thirdly, is this thread still going? Seriously, the thing about the internet is, it is huge. Why the mania about this one, tiny, site? No-one is nailing you to a chair, eyes wired open, forced to engage with it, Clockwork-orange stylee.
It really does look like weird, bullying behaviour, by members of a vast, powerful forum, of a teeny, tiny little forum.
