A slightly different spin on Mayday - again from Matt Cutts. This time it's in the one hour site review video from Google I/O [mattcutts.com] - at 49:50 minutes in.
In this response he does mention long-tail, but he puts more emphasis on the idea of returning what Google feels are "better quality sites." He keeps saying "sites" rather than pages - so that may well be a big clue to what's going on.
