If I see a post and I want to see more posts like that in that community, I updoot. If I want to see less posts like that in that community, I downvote. Nothing more complicated than that.
So if you post a cute cat pic to a community about cats or cute things, I’m updooting it. Not even super concerned with how well I looked that specific pic, I want to see cute cat pics there and you provided one so you get the updoot.
But if I’m in a discussion-based community and you post something with a clickbait title, I downvote. Doesn’t matter if you’re technically still on topic, I want to see less of that nonsense so I downvote it.
Romance is when you meet someone who makes you want to cross lines you don’t usually cross with others. Sex is the really common one, of course, but I’d argue it’s all the rest of the emotional and social stuff that makes it *romance*. Sometimes it’s exciting, sometimes it’s scary, sometimes it’s really warm and comforting. But what makes it a romantic relationship rather then just a friendship is that feeling of wanting to cross a line that you wouldn’t cross with anybody else.
