Hello all, I've been on steemit for just over a week now and while I've gotten a handle on most things on here, there are just a few questions that I have about things I'm still unsure of. My first question is what exactly is "delegation" under steem power and what causes that number to fluctuate? Secondly, I know SBD stands for Steem Based Dollars, but how exactly do they work? What's their actual value?
