I don't have much to add except that I agree. Certain labels seem to be fetishized at times (BN isn't the only one), whereas there isn't much of a mystique surrounding Prestige or Riverside. That said, there are a lot of great albums on BN.
If we're talking #s, 8 of the last 100 CDs I've purchased were recorded for BN.
ed: Wanted to add that hey, props to Blue Note for maintaining and cultivating the mystique. If it leads more people to listen to jazz, excellent.
