I'm so grateful that our witness @blockbrothers consists of four people (@bennierex, @eqko, @s3rg3, and me) and that all of us have the same goal and that is to add value to the blockchain.
It would be simply impossible to run it the way we do on my own.
It would simply be too much for 1 person.
Not only does our witness server (+ backup) has a perfect track record of 0 missed blocks, but we also maintain our Steemify server, we run a seed node, we build applications (Steemify iOS, STEEMTURBINE), do promotional work for our witness, make blog posts and try to educate as many new Steemians about the Steem Blockchain every day.
It takes many many hours.
And now we are expending our endeavors even further when we hired an Android developer to start building Steemify Android for us not long ago.
How cool is that! I'm over the moon.
Not bad for a witness that is less than 2 months old. (the witness, I am personally involved with Steemit since July 2016).
I talk about it more in my vlog (@7:10).
