I do not disagree with your voting philosophy.
My only point was that it is better to vote for some witnesses who at least are trustworthy and competent to secure the chain even if the votes are still up for grabs by witnesses who do something more, than it is to leave the votes idle until you find such witnesses.
BTW, my witness account is pretty much only used for the witness itself, and I use this account for the social app. While I don't post all that often, I do engage regularly in comment threads (and as you noted, votes and especially downvotes).
