Thanks for inviting me to Steem buddy, it looks really interesting. I'm sure you can save me a ton of time by answering a few quick questions.

1. Where does the cash come from? The speculative crypto part of it I understand, but we are also earning something that is pegged to the $USD and I'm confused about where that money is coming from. What pegs it to the dollar? I assume the rest of it is just speculators or supporters who want to buy Steem and that creates the price for it on other markets. Is that the only reason that our posts have a monetary value?

2. Why isn't everyone automatically sharing everything they do here on Steem? Is there a reward for posts that are exclusive or any reason to make something exclusive?

3. If I were to describe Steemit as "Reddit, but with a cryptocurrency attached to it where the 'coins' are generated by users creating content and discussing it rather than computers solving math problems." how far off would I be and what would I be missing?
