I think the most important question there is the last one, which is about how Quantopian's interests matches the interest of our members. We're going to provide services that are valuable enough that our members will be willing to pay us for them. Those services will probably be the ability to trade stocks using algorithms and access to additional data sources (more than is currently available to free). In the long run, that provider/customer relationship only works if our members are satisfied with the services we deliver. That is what aligns the interests of Quantopian with our members. Is that the question you were asking?
As for our governance, it's pretty vanilla. Quantopian is a business like most other startups out there - there are a handful of shareholders who elect board members, and the board members hire the CEO, and the CEO runs everything else. No deep mysteries there.
As for the fist, it's chunk of nuance. It's poking, part serious, part fun, at the Wall Street establishment. We're trying to dramatically change the way a lot of firms do business. On the other hand, I think it pretty quickly becomes obvious when you learn about us that we're not the IWW nor Occupy Wall Street. So why co-opt such a powerful symbol for a blog post by a fin-tech startup? I threw it in there for all the usual marketing reasons: it catches the eye, and it prompts a question that makes one want to read the blog to find the answer.
