My first ever post

As what my title states, this is my first ever post. I am a new member here and I am still trying to explore this site. I am trying to learn about this site. I hope I can also learn some tips from the members here.
I heard about this site from my brother-in-law but he is also learning about this site that is why he can not give me any tips yet.
I need to have more reading to understand the rules and regulations of this site but I am also open for more tips from other readers or members.
As what I understand, Steem is a new currency which can be converted into other currencies. The first thing that caught my attention is that we can earn from this site. I have seen post with the amount earned from the upvotes and comments.
