I saw this particular situation once before but wanted to question it today. This question was migrated from Stack Overflow to Super User, but it would serve better value at Ask Ubuntu.
When I commented on this my comment was deleted. So how does one decide where a question should be migrated to? Why when a question is flagged to recommend a move to a better location it doesn't list all the choices? I was under the impression that content should be migrated to the best site and also limit an overwhelming amount to Stack Overflow.
