The level of entitlement the internet has created baffles me, but it really shouldn't. I love the "buying a skate video" comparison, but most kids these days don't even know what one of those are -- or that they used to cost money.
The show is still free. If you want to pay for the extra shit, go for it. If not, quit whining.
These dude's deserve to see something for the time/money they've put into it. If that bothers you, you've clearly never created anything you're proud of. We're lucky any part of this is still free. I challenge you to consistently put out a comparable product without a source of income tied to it, or the desire for it after producing it.
Regarding research: Get a better argument. Brink researched the shit out of guests before Weekend Buzz interviews, and people still found reasons to shit on the show.
For real, though -- $1. If you can't afford $12/year for something you really think you need and enjoy, you have bigger problems than The Nine Club charging $1/month for extra content.
