Just found out that if you add the postid of an answer after stackoverflow.com/questions/ID then stackoverflow redirects to the stackoverflow.com/questions/questionID

This is a fantastic feature that we could implement into the core!

(I could also write a plugin for that, but it's so awesome to deserve the core :) )

PS: At Stackoverflow it only works for Q and A, we could also include Comments ;-)

Q2A version: 1.8.0

I have been looking forward to implement this without success.alternatively I want to do away with question id for good and have something like domain/here-is-question

The following is one possible implementation. As long as it is not in the core, copy it into your qa-theme.php:
