Always cool seeing and hearing about SN's insights into things so far, great transparency.
I agree with all of the AMA/outreach stuff. Those always seem popular. Perhaps paying for that could be worth the marketing expense.
Unsure about paywalled content though. I personally don't see value in it (i have never paid for a paywall post or put my content behind one). I zap a decent amount here but probably would not contribute to paywalls. I can very quickly bet those will be trivially reposted here unlocked so you're going to have to battle copyright.
In general quite content with SN, glad to see growth and more experiments.
