Scheduling
I agree that Independent Lens, Nova, Frontline, News Hour with Jim Lehrer, and Masterpiece Theatre are good series. I would add to the list Live from Lincoln Center, André Rieu concerts, Bill Moyers' Journal, Exposé, Washington Week, Antiques Roadshow, Business Week, This Old House, Now, History's Mysteries (which disappeared too fast: didn't PBS formerly give shows a chance to find their audience? That was always a big complaint against the commercial broadcast networks). I also liked TV Pioneers; there are certainly others to be covered, and radio performers/reporters would also make for an interesting series (though less visual, I suppose). I don't like seeing the same specials aired many times during pledge drives; keep changing the content during those times to air as wide a variety as possible.
BBC News helps give an outside view of the world, and similar shows from other parts of the world, possibly such as Mosaic, with which I am not familiar (perhaps a daily slot that would feature news broadcasts from other countries on a rotating basis) would help give U.S. viewers a different perspective on events at home and elsewhere and how the rest of the world sees us and each other.
