Witnesses.... DO you know them?

So I have been on the site for a bit, and there are these people called witnesses. I guess they run some stuff that keeps the Site running. BUT did you know the Top 20 get paid for that... LIKE 250 Steem a day.

I understand that we need people to do it, but It is definitely something I am going to look into. One witness also posts, and they are not very good, copy and past things. It was on the top of trending the other day. WHO IS WATCHING THE WATCHERS.......
