[This question][1] was closed as off topic, but was not migrated.  I (incorrectly) decided to vote to close and migrate to Stack Overflow, but the question was not migrated for quality reasons.

I understand [Jeff saying][2] "don't migrate crap", but can someone actually give guidelines on when questions that could otherwise be migrated should simply be closed?  This seems to be a point that close-voters tend to miss.

### Edit
Per [this question][3], there are other reasons why questions should not be migrated.  For example, a question should not be migrated to a beta site unless the site has established itself.  Can you list any other reasons for not migrating questions, in addition to low question quality?
