I trust Justin Frankel, I don't know you, previous team or not.. The world can go on using Winamp 2.x forever and be just fine, its GRAS. If you're bringing something that isn't that, previous dev history or not, you're going to have to differentiate yourself from the folks who are also putting out winamp-alikes.
I'm not trying to be a jerk, that's just the reality.
Knowing what the code I'm running is doing is helpful in swaying me to your direction, even if that's not what you claim to be aiming for.
> should I be expected to do that when I'm the only one working on my Winamp reimplementation
Let us know when you want to change that. We're talented, and generally nice. Maybe some day you'll want some help.
