I thought the accepted answer is always listed first - here it is second. Huh?

Question

How is it possible that this question has the top-voted-but-not-accepted answer listed first, instead of the accepted answer?

What's the easiest way to get text onto a Kindle?

Answer 1

In this case the accepted answer was posted by the person who also asked the question, and self-accepted answers do not receive the preferential treatment during sorting that an accepted answers otherwise would.

This is intentional, and has been the case for self-acceptance since it was introduced.
