I’ve been on the creator side with 1M+ followers and the amount of times someone has dropped a kind note like that can be counted on one hand. It’s such a breath of fresh air compared to the hate, criticizing and general unpleasantness that is so pervasive when dealing with online communities - even my own.

As a result, I make it a point to send notes to anyone if I’ve enjoyed their work, because I know how much its meant to me, that I hope to pass along those kind, appreciate feelings.

I'd be curious to hear more; I assume you are distinguishing a positive note (email etc) from a positive comment?
