Sorry, it's just I'm trying to keep it among known people or people who are vetted by people we know and trust (that also includes IRL identity etc). Like I said, when I see momentum and people deriving tangible benefit from it, I'll take it public! :-)
The second you take it public, it will get destroyed.
It's the classic "I don't want to be in a club that wants me" vs "I want to be in a club that doesn't want me"
AKA Eternal September. The quality of an online community is inversely correlated with its popularity.
Maybe make it read only for those who are not vetted? That would keep standards high and you can have a different place where everybody can comment add a source of future members.
