I was reading this question which was migrated from Math.SE. Although this question was closed as a rant it made me wonder about migrated questions.
This question was asked by someone without an A.SE account (I think that's the case) so, for example, the username shows up but there is no link. I'm not sure if that user will get comments or answers. I also wonder if that user can (or would) ever accept an answer.
All of this begs the question, when non-A.SE-users are the asker of a question, should we delete and re-ask the question so that it belongs to someone who can actually answer clarifying questions and who can accept answers?
