I’ve been seeing more often (and others have posted the same) that some of the elements of “Reddit etiquette” seem to be taking over here. Luckily I can still find discussion comments but it seems the jokes and general “downvote because I disagree” are slowly taking over.
So the question becomes is it the size or the functionality of the site? The people or popularity? What’s your thoughts?
You’re assuming that downvotes only come from individual users with good-faith opinions there.
Relying upon an automated system to decide the “value of a conversation” is, and will continue to be, an open invitation to gamify, metagame, and manipulate such automated systems, just as it was on Reddit and elsewhere.
