Re: Unrelated: Shakespeare question
People play-acting with "how it *really* sounded" videos and stuff like that, even if historically informed, are awesome. There are videos of people caterwauling through the Iliad with full restored "Homeric" pronunciation, insisting that their ideas of how the pitch accent sounded. (In reality some of it can be conjectured philologically, but by no means all, and nobody knows how it sounded.)
If they get some LARPish thrill out of it, sure, as weird a hobby as it is. They could be Civil War reenactors.
You're absolutely right about pronunciation drifting. I just realized I've written a sort-of reply to both you and Joe.
