I've seen a few posts that have been new info to me today. Those particular posts had comments about it being old news. Berating the poster. Basically trying to make the OP look or feel stupid. Just because you know info doesn't mean everyone else does. Posts move along quickly and are easily missed. I'm on here several times a day and i miss tons of posts. Sure, if it's incorrect lets fix that, hell that can even be done politely. If you know, don't be an ass, just move on.
Perhaps this is the new liberal shill tactic! Make posters feel stupid so they fear posting again. Seems like a libtard thing to do. Damn we need more golden rule in the world!
I'll step off my soap box now. Cue libtard attacks....
Why is "karma" even visible here? Might be best to just hide those numbers as well as the up/down-vote numbers on comments and posts. Let people vote but keep the numbers hidden to discourage this from becoming a popularity pit.
