My main keyword terms have hung in there
This report - and a few other posts around the forum - make me wonder if we had Panda late on Oct 13 and then another algo change on the 14th. Even when Panda lets a site rank for certain major keywords, the main effect I've seen hits big search terms. Some pages/keywords may be exempt (or even boosted) but Panda does not usually show as just a long-tail impact.
