I don't know what the answer "should" be to all of these, but I do know it grates on my nerves when people are all like "it costs nothing to tag!" or "just check the list!" or "it's so easy, if you won't do it you're just a bad person"

Just because something is easy for you doesn't mean it's easy for everyone.

And it is very very disheartening to consistently be the person who "looses" in a case of competing needs :/
