While I'm on JRB's side here , that second article that was linked seems to have some contradictory remarks:
The problem with this line of reasoning is that if everyone anoints themselves as promoters ... then the promotional value is worthless because everyone is a promoter and no one is paying.
As for everyone doing it, that simply isnt true.
One thing that amused me when I read this whole exchange a week or so ago was the fact that Eleanor was trying to educate him about what it's like to be a struggling or "starving" artist -- as if he'd never been in that situation. We sometimes forget that even the successful folks (generally) also started out with nothing and worked hard to get where they are.
On a side note, I highly recommend The Last Five Years
