Best way to update old answers when links have changed?

Question

tl;dr : I commented on an old answer to show corrected links. Is there a better way?

This has recently come up for me because of the accepted answer for this question:
Is there a way to autodetect when a display is disconnected?

There were at least two outdated pieces of information which required updating, and for now, anyway, I've just left comments indicating this.

I would probably just edit the current answer if there was a one-for-one link replacement available, but I don't think that is the case here. Furthermore, I can't test the updated information because I don't have the set-up described in the question.

Should I nevertheless have put the updates inline in the answer, somehow, or are comments a reasonable way to do this? Is there a better way?

Answer 1

Sure, just use your editing powers -- you have over 2k rep so click edit and edit generously to make improvements. What good are superpowers for great justice if you don't use them?! :)

( and, even anonymous users can submit suggested edits: http://blog.stackoverflow.com/2011/02/suggested-edits-and-edit-review/ )

Answer 2

The Review system should have an option for searching for posts with deadlinks. I don't know if this will overtax the StackOverflow servers, though.
