Joining steemit,i was very excited and confused ,quite confused because i just knew that am making posts and viola ,no idea thereafter.I made my first two posts and had nothing ,very few upvotes,and i had no dollar,i felt it wasnt worth it and so i gave up,then some days ago ,a friend of mine @xpressng just told me that one steem dollar was above 3500 and i was like ,woah..then i made my introductory post again and viola before 2 days ,i got 6sbd,i was like nice ,but i still had and have lots of questions.
These were some of my questions and i guess would bother newbies

1,whats steemit about
2,how is money made on steemit
3,what is steem power
4,what is steem dollar,how is it converted to cash
5,who is a whale,and how do you become a whale
6,how do people have lots of upvotes but low steem dollar and why do others have low upvotes but more steemdollar
7,how to you make sure that enough people see your posts and upvote it
8,what are the tags for,and how do they help with increasing your posts
9,how much fun steemit is in general etc

So many questions ,but my advise to all newbies is to go with the flow,you will love it,if you love writing but its really nice to see so many upvotes and comments on your posts,.....this posts is for contributions from everyone,comment on the questions to help the newbies feel more at home
