It sounds like you'd like to think your community-of-choice is unique, but get over it. There is no "we" here, nor is there some amazing comment quality optimization going on. This place goes hive-mind like any other forum on the internet. "We're" not special.

All communities are unique. This is the only community I know of that obsesses over a guy who makes bingo cards for a living. That doesn't mean we're necessarily better than other communities, just that we have our own specific approach to downvotes that people coming from other communities might be surprised by. (In particular, we usually downvote tangential/uninteresting comments, memes, and humor -- edw519 is an exception because his humor is typically both topical and side-splittingly entertaining.)
The person in question posted one of those types of comments, and then asked why it was being poorly received. He has now been educated as to what "we", in aggregate, are looking for.
