I'm glad you asked. Everyone should get to know witness voting. It is like a political process to vote our leaders that make decisions for Steemit in behalf of STEEM Inc.

I wrote an article about it. https://steemit.com/life/@socky/witness-system-explained-simply

After reading my article, please come back here and promise one of your witness votes for the cause. It won't cost you anything and you have 30 of these votes that you can always change.
