Interesting information on Witnesses! Gives a better understanding of how SteemIt works "under the hood". I will be reading up on the various witnesses and placing my remaining votes. In the article from @pfunk, there is a link to steemd.com/witnesses. Scrolling down on that page, I see a bunch of individuals that are 'greyed out' (https://www.screencast.com/t/yo2xokrW4).
What does that mean?
