I really liked Mixergy. I turned lots of people onto it. When you decided (almost out of the blue) to turn it into a strictly money making venture for yourself I felt burned. I thought you were following in the footsteps of Charlie Rose's interviews, Paul Graham's essays, or one of the dozens of great Podcasts that exist. Something fairly altruistic that may generate money for you, but not as its primary goal.
It turns out you were really just building an audience so eventually you could upsell us into into some kind of self-help guru educational pay site. Not that there's anything wrong with a site like that, but it's not the kind of site I would ever use, and certainly not something I would ever actively promote.
I think there were a dozen ways you could have made significant money off Mixergy that wouldn't have felt like bait-n-switch. Instead you took the easiest and lamest possible option. I don't visit Mixergy any longer and I don't promote it anymore.
For your sake I hope you're really successful with the path you're taking. For mine I hope someone moves in to take the role I thought you were filling: The Charlie Rose of the startup world -- not the Tony Robins.
