ALthough 'setting up a witness' feels like something very huge (and I was very excited for this post the last few days), in the overall scheme of things it's only 'another step' (with a lot of importance! but another step after all).
Even without the technical skill, being part of an open-source community can leverage every one of us as individuals. That's the true power of 'the swarm'.
There's no problem out of reach for everyone :)
