A few months ago, LM_NET was all a-flutter over the separation of children's books from the main NYTimes bestseller list. I argued that it was (to quote Martha Stewart) a good thing.
So where's the furor over the new mass-market and trade paperback lists?
Lists are essentially meaningless to anyone except booksellers and authors. Unless you're looking for ideas for "what to read next" (or to give as part of BAFAB niceness), why does it matter how many lists there are?
