Same here, FB blocked a post today, because it is conservative, when I tried to post it, by saying the link was bad. I snuck it in, in a comment, and it worked just fine!
As far as the witnesses, it would be fun to help steemit with hardware (I will have to move to the new land first, :( but I intend to ahve a high speed link out there). I am an electrical engineer, and have a small accumulation of computers here. Can probably make a dozen or so run with what is here. I have four where I can touch them right now, LOL!
I'm witnessing the birth of a witness!! It's so beautiful!! ;)
Witness or witless, remains to be seen I guess, LOL! But it would be fun.... :)
