I miss reading the 100 page threads on What.CD about which of the 40 different rips of the White Album was best. Alternatives have popped up, but it saddens me that we lost all of that collective comment history.
I was part of What.CD (and its successors), but if I'm wondering which edition to snatch, I usually search the Steve Hoffman forums [1] and look up the Dynamic Range DB [2].
