Should the users get a lot? I'm certainly not here because I think it'll make me rich, I'm here because I think this is a valuable community whose insights and opinions matter to me.
Our previous discussion about b-corps segues nicely with rob's insistence on open-sourcing. That Pando article about Digg v. Reddit also points out that Craigslist still exists because they never prioritized monetization. I think you guys are in an entirely different paradigm than Reddit in that you aren't interested in a sale and you aren't interested in getting a bunch of TED talks out of this - you want to build a lasting, worthwhile community that isn't a financial drain on you. That gives you a lot more leeway.
I'm 100% sure Hubski can be operated at a profit such that it will provide for the livelihoods of those who devote their time to running it. Part of the reason is that I think it's a system with a great deal of extensibility and scalability; the other part is that because of how you've arranged it you just don't need a lot of staff.
I'm equally 100% sure that Hubski will never be bought out for millions of dollars. If you're cool with that, the future is bright.
