I'm so with you there! There were SO MANY pronunciation threads on HPFGU and it always drove me CRAZY. Like, how could anyone not understand that it's Her-MY-oh-nee? (or In-fin-EYE-tus, ahem? It's In-FIN-ih-tus, hello.)

I'm not necessarily 100% right all the time, but jeepers, folks, use some common sense. And if a name is a real mythological one or something, LOOK IT UP. There are phonetic glossaries out there, even on the intarwebz.
