witnesses are your representatives on steemit for decision making and so on just as Governors are representatives of their state citizens and President are representatives of the whole country.
Witnesses are our spokes person on the steemit board.
So you can choose your representative today by casting your vote for @steemgigs which am sure you do like to be your spokes person. One more thing, you can vote as much as thirty times for the candidate of your choose. I hope this answers your question?
Thanks for this clarity, you explained it well. @steemgigs should the first witness we'll vote for.
I have voted, have you?
