IMO you see the same issues when you have Google start optimizing ads for user signup. We've had a huge amount of user growth from ad spend. But not really the users we want, for the most part.
Any marketing to people who aren't in New York, or people who aren't rich enough to spend $100 a head on a meal, is largely wasted.
Worldwide viral coverage on Reddit and Twitter? Youtubers and podcasters singing my praises? Meh.
But sponsoring the New York City Ballet? I'll get far fewer hits, but the hits I do get will convert at a much higher rate.
