I like this non-relativist stance. Simply stating YMMV often kills what could have led to a good conversation, thus possibly preventing us from learning more.

I'd like to couple this attitude with the great advice of having "Strong opinions, weakly held". (http://bobsutton.typepad.com/my_weblog/2006/07/strong_opinio...)

If YMMV is getting abused, that's a problem with the abusers, not YMMV. I've always taken YMMV to mean "your use case may be different than mine; I don't know everything, but this works for me in this situation."
