Oh sure, I know why they want to do it that way. But the sad thing is, they could do price differentiation even in a purely self-service model. It's not a perfect analogy, but look at something like AWS - no sales-person there, but customers price themselves into different segments based on what they sign up for and use. I can't help but think Twitter could accomplish their pricing goals without needing a human in the loop on their end.
