HN AMAs unfortunately seem to be a non-starter. I can definitely sympathize with blocking reddit for productivity reasons, but it's a connection with your target market that shouldn't be ignored.

I like your idea, and I love your goal, but it's going to take more than that to make me a customer who forks over hundreds of dollars. You've got the attention of the technorati; I'd first focus on how you can convert them to paying customers, then deal with the plebs later.
