Welcome Queen Bee!

1. When you post and people vote for you, you get rewarded. The more SteemPower someone has, the more they reward you get.
2. Blockchain is a public timestamped database that cannot be altered by anyone. No one can censor it. (Not like Facebook or twitter)...ideal to preserve free speech.
3. Yes!

In many ways, I try to keep it simple. This ia my attempt: If you write something that people like, they upvote. The more attention you get, the more likely you are to make money on it. The content creator get 50% of the amount of money you see at the bottom of the post. The other 50% goes to people who upvote.

The reward for content creator come half in SteemPower and half in SteemDollars.

SteemPower: is your voting "klout". The more you have, the more money you can make by upvoting.

SteemDollars: can be exchange for $1 US.

First payout July 4th and then every 24h. Whatever payout you accumulate until July 4th will be paid then.

If you work on creating a "Steemit for Dummy" you could post 1 chapter at a time on Steemit and I am sure you will be handsomely rewarded by the community. :-)

Then, I and other would gladly compile it and promote it on social media.

Cheers!
