Someone post this https://steemit.com/steemit/@donkeypong/still-confused-by-steem-steem-dollars-and-steem-power-the-power-plant-analogy on my post. That is quite complicated. I have to take time later to understand it well.

TBH I have seen that you can earn money by posting content, so I wanted to try, to see if this is a joke or not, but I'm quite confused by the system as a whole.
