I do remember the witness you are referring to. I thought he meant well, but it did not seem sustainable to me. Granted, he was flagged to death, so he literally had to stop, it was not the market per say.
I keep on learning, almost weekly that most people are not too informed of what a witness is supposed to be doing in the first place, hence why this subject will probably never go away.
I've done a few posts about witnesses and why people should vote. I support those who I see doing good things for the platform.
