I don't know much about the witness, I learn more from the comments. I understand they're miners.
I understand the advantage of the witness being voted but I didn't understand what my advantage is to vote for a witness.
My question for @fulltimegeek and @underground , is: What changes for me if I vote for witness X or witness Y?
I mention that I voted for @fulltimegeek (because a friend asked me) and I voted for more witnesses who have developed different applications that I use.
