The edit in question has an edit summary of 'broken link'. Looking at the markdown, I can see that what the suggester did was just remove the broken link altogether.
I was thinking about rejecting as too minor or invalid, but then I saw that the post is really popular - ~180 up votes.
Surely, I though, no post that popular should have a broken link. And so I accepted.
Now, however, I am wondering what I should have done. Accepted because it does fix the post, or reject because it was probably the author's job to fix the link.
What do you think?
