I tend to upvote a post when it Links an interesting article or provokes an interesting conversation, and only downvote them when they voice an convectively bad opinion (like, bigotry or other unjustified vitriol).
I tend to upvote comments when they make a good point or at least try to support their argument, and only downvote them for the same reason as posts: when they are trolling, being unnecessarily aggressive, or trying to justify bigotry with fallacious reasoning or something
What about you?
No one corrects “octopodes” to “octopi” and if they did I’d have to assume it was sarcastic.
But yeah, like any self-respecting Classicist I obviously upvote correcting “octopusses” to “octopodes”. That’s just common sense!
