We've been building Tampa Hackerspace for the past four years and much of this is similar to advice I give. The "ten people" to start is close. I tell people you need at least 100 in your broader community and at least 10 committed to the point that they'd put money into it. More is better though. We probably would have started a year later if we hadn't had a firm "just do it" person on the board. We got lucky with our initial landlord and very lucky with our current landlord. Everyone we talked to would tell us how easy it would be to find space but it was a huge hassle finding someone that would rent to an unproven organization without much cash on hand. Using recurring billing via Paypal (now considering Stripe) was a huge help. Of course we meet on Tuesdays. It's been painful but we meet every single Tuesday. There's never any confusion about whether we meet this week or next week. Every Tuesday. The "Sine Curve" pattern worries me and I can definitely see some of our shops / areas becoming cyclical.
