It's crazy that even with Ron telling Dave to stop embarrassing the tech community with his unprofessional classless writing - he still did it! That in itself is truly classless
I believe this email was written after Dave posted his defense of the meetup.
Yes, but Dave's accidental tweet to the whole world came after Ron's email, didn't it? That's what really makes Dave look like a webtard - Ron told Dave not to "cause silicon valley more embarrassment with your unprofessional classless writings", and then Dave sent out a tweet doing exactly that!
That was a mistake, meant to be a direct (private) message to someone on twitter, probably a fellow "super angel".
