Way up there, Snuffy asked about usage. If you come back, Snuf, YMMV was in an answer to my question about 80/20 bronze guitar strings, and it referred to how long certain ones might last and how pleasing or not-pleasing certain ones might be. The writer cited his experience and said, YMMV, which I now take to mean, "Don't expect your experience to exactly duplicate mine."

I'm learning all kinds of things in Mudcat Station. :-)
