That is to say -- I've found that while the sheer volume of mass-produced crap has gone up (including but not limited to music criticism), so too has the sheer volume of rare, underground jewels. I don't know if/maybe doubt discovery has been cracked yet.

I even wish the elitism still existed. I used to go to Pitchfork, Coke Machine Glow and sites of that type to read about music that wasn't getting covered elsewhere. Now it's basically Rolling Stone, but worse because it pretends to be counter culture while devoting endless posts to TSwift or Drake or any number of artists that can be heard on every major radio station.
