Hey @darkiller18! I am also new to Steemit. I have been on the platform for about a week and I am gaining a lot of knowledge on here. The rewards are just a plus. The beginner guide you see when you log in is very informative and goes over a lot of questions you may have. To start, I would begin by going on the trending page and read any posts you find interesting. Be sure to upvote and comment to earn rewards too! Feel free to reach out if you need any more help. Steemit to the moon!
Maybe @cryptoevo has some tips for you as well! He was a major help to me when I started on Steemit.
