Someone just started a thread in the Chronicle forums about a question I had last year. Do you say in your cover letter that you're really interested in a job because the school's near where your partner works, and it would mean the two of you could be together? Almost everyone in the thread says, no, don't mention your partner. This is interesting, because it's exactly the opposite of what the Future Dr. Mrs. Dr. PGS's placement chair told her last year.
As deadlines get closer, the flat-out contradictory advice starts to make me insane.
