The question Is ‘USAers’ just an ordinary English word today? has, at the time of writing, a net vote of +4. On the other hand, my question Can I use "US-American" to disambiguate "American"? If not, what can I use? has a vote of -4. I don't quite understand.
What distinguishes a good from a bad question? In particular, what makes my question on US-Americans so bad that it has a net vote of -4, whereas the question on USAers has a net vote of +4?
I would like to learn to ask better questions.
