I really like Steemit but I still have questions about it that I just can't seem to figure out. Some of these are basic use questions while others are more generalized. Here are a few of my questions about the Queen of Crypto Social Networking (with the Bitcoin forum being King of course).

1. How do I look up individual users on Steem?
2. What is  the best way to gain more followers and get more upvotes?
3. Is it worth purchasing Steem Power early on? Does the Steem Power seem to pay off?
4. What are the most popular topics on Steem and how do I pick them out?
5. Is there anything else I need to know about Steem?

Thank you!
