One thing about curation rewards that was never explained to me very well was that a new user will hardly get any even if he curates all day long. When my account was worth $50 I could literally curate it all the time and not get a single cent even if a post was worth $500. Now that my account is worth a couple hundred dollars I can make a few cents a day from curating, and I know once you have a few thousand SP you can make close to a dollar a day. It really is a system that rewards having the most steem power, and I intend to increase mine significantly.
