Maybe we should show who upvoted a question or answer (similar to Quora).
Why we should:
- Extra way for people to be visible on the site. Even if someone isn't asking or answering, they can be visible with their votes.
- Incentive to vote. If I see a great answer, I would want to be associated with it by voting (even if I don't have a comment to make).
Why we shouldn't:
- Some people might want to vote anonymously.
