Ah well, couldn't wait - installed the new quotes just now. We now top out at 40,000 different quotes in all - up from 27,000 previously.
I've gone through all these new quotes with a fine-toothed comb, checking each to make sure it wasn't a duplicate of something we already had, and doing my best to weed out spelling and transcription errors. That said, I'm sure a few "oops" have slipped through the cracks. Please report bad quotes if you come across them.
Thanks, and happy solving!
