I don't mind a slight hint of diacetyl in some beer styles, as long as it is quite slight, but this is a matter of personal preference. I know a lot of people HATE it with a passion, and that's their choice. I'm about as sensitive to it as many good judges are (I'm Certified) so I don't think I'm missing it either, but of course there's always somebody else out there more sensitive and more picky than I am. So yeah, it's possible I'm not perfect. However I do try to be.
