At a higher level, I disagree with your point that you can get away without the "hassle" of promoting your content. You'll always have to do some kind of promotion of your content, even if it's really good. And, if it's bad, no amount of promotion will get it anywhere.
IMHO, the main point I'm driving at is that there is no "free lunch". You'll always have to promote your content in order to gain a followship. It's just a fact of the web.
