Thank you for taking the time to reply, I look forward to your answers in future posts.

When I go to https://steemit.com/~witnesses, I see you're currently listed as witness number 13. I also notice there's an option where I can cast a vote for a witness, which makes me think I should know something about their relevancy. Whether it's here in this comment thread or in a future post, can you please answer this question as well: As a steemit.com user, what do I need to know about witnesses, if anything?
