My opinion is that it's courteous to ask the interview subject if they're comfortable with their interview being promoted on twitter. I'm not sure why it being public here or elsewhere is relevant? A members only section didn't exist before and now it does. Whatever people want to do is fine with me but again the option should be given to keep it private to the forum members if possible. Again, I just brought it up because posting things on twitter, facebook, reddit, wherever potentially exposes people more than they want to be exposed.
@Enoch can you remove my interview from the thread? I'll just stay out of the conversation then.
