One part I did not know was the internal workings of Steemit, how Steem and value were assigned. I must admit I knew very little of anything mentioned in the blue paper and will likely revisit as I learn more. It will likely make more sense as I learn the basics of Steemit.
The most valuable, to me personally, is knowing about bandwidth and steem, how to use it frugally instead of wasting. Thanks for the info!
