I think one of the keys for me — when it comes to other people's posts/comments — is whether the post actually taught me something, or interested me in some way... or, at the very least, did the post tell me something about the author and what makes them tick.
And sure, Steem is messed up and weird... and I totally understand that not everyone will see it through the same lens of perception as I do, and that's cool, too...
