What The Heck is Curation and How Does it Work?

Wzup wzup wxuuuuuup!!!!!!!
Mt fellow Steemers how is it going? I've been hearing about this activity called Curation with Steem. I've been researching it and coming up empty handed in my understanding on how it works or how to get involved. I see there are many avenues that Steem has provided to capitalize on and I'm working to learn as many as possible. I have yet to fully understand Steem vs Steem Dollars vs Steem Power????? What the difference in each of these and really how each benefit and how to use. Now I've been attacked by Curation and what it is and does????? I'll spend the next 365 days researching until I get the hang of it!!!!!!!
Hard work and Dedication!!!!!!!
