I too am a huge B/J fan, but J/M are totally my not at all secret secondary pairing. I didn't write much QaF material, but I am amused looking back that I wrote more for J/M than B/J -- and yet if you'd asked me I would have said B/J were undoubtedly my OTP.

There's just so much to explore with the Michael/Justin pairing. I think it has the potential for such awesome fic, and I wish more people would jump on the bandwagon.
