I found this question "A question about hyperbolic functions", where the OP accepted his own answer with no upvotes (so far). The strange thing is that the accepted answer doesn't show up on top, no matter how you sort it.
When I look at one of my own self-accepted answers, like this here "Two Steps away from the Hamilton Cycle" my answer is top.
What's up with this post? Or is it just me seeing this...?
PS: When was the mapping from pure M.SE shared links to post names introduced? Cool thing...
