FYI (and FWIW), a small point of English usage: the usual expression for distinguishing good from bad in a large quantity of similar material is "separating the wheat from the chaff." It's a nice word, so I thought I'd share it. "Tares" is a perfectly nice word, too, but it's far less common, and possibly obsolescent.
