I can’t say I never downvote anyone but I get into these comment chains from time to time where really no matter what I post whoever I’m talking to downvotes every response but I generally shy away from downvoting even things I dislike. I don’t want to fall into an echo chamber where all I see are only the things I agree with.
I do once in awhile but honestly I hate public voting. I would not mind a private ranking system for the feed that worked the way trustcafe works. I mean peoples public voting won’t effect the way I peruse the feed but yeah some things are bad enough that I feel I should hit the down arrow. I upvote practically everything though as it marks it as read for my feed view.
