I wouldn't say every thread at all, but maybe we read different kinds of submissions. Plus many things are repeated ad infinituum. I can guarantee any discussion on wind power will have someone saying we should be going nuclear. Every discussion on electric cars will devolve to a discussion on Elon Musks personality, every discussion on facebook will lead to a mention on privacy. People have opinions, they've come here to express them, most of it will retread old ground, if there was nothing new to add, 90% of submissions could just be linked to the original discussion, that isnt what happens, (although old threads are generally linked to) so it seems reasonable if we're going to re-have all the other discussions, to re-have this discussion. And finally, it seems to be the rule that to be downvoted, an opinion has to be wrong and/or offensive. So if there is a downvoted comment that seems to be neither I'll then take the time to find out if I was wrong, so for me, downvoting comments that you just don't want to read, just adds noise. I'll admit that that's personal to me, and its entirely likely that others see downvotes differently, that is an annoying consequence of votes being such blunt instruments.
