I see all the positives, and I'm on board. I just got a little freaked out at getting 10,000 for a sub right at launch. Maybe you could have a baked-in grace period of a month or two? (Point number one sounds like you've already thought of this)

Anyway, probably not a big deal, no matter what you choose. If a Stacker really believes in their sub then 10k is kind of nothing to invest.
