Thanks a lot for the tip :D I will try to keep it up to 4 posts per day. Btw, I still don't get all the details about steemit xD Especially the ones about steem power and this dollar numbers under every post and also I don't get those potential payouts...

Steemit power or SP is the influence tokens. The higher the SP, the higher rewards a post that you upvote. The $ under each post is the total value of rewards per post that later on is distributed as 85% to the author and 25% to the upvoters. For the authors (the 85% of total reward): 50% will be given as Steem +Steem dollars and the other 50% is Steem Power. keep in mind there are 3 currencies in steem ecosystem: Steem, Steem Power and Steem Dollars :) for more info i would suggest you read the whitepaper here: https://steem.io/SteemWhitePaper.pdf
some of the economics policies are changed so you might want to check this: https://steemit.com/@steemitblog :) for more info, you can ask in steemit.chat :)
