Thanks for the suggestion. No in this case both domains have been around for a very long time and both were PR5's (now wxy.com is a PR6). None of the pages which disappeared were redirected (in fact they were the ones which I specifically had NOT yet moved to the 'new' domain since they were ranking so well (all top #1-5 in their keywords. Now they aren't even in the index and GBot hasn't visited the domain since 2/28 despite re-submits. (Is everyone else getting an "about.htm?zzzz not found" error when trying to submit on G?)
It's looking more to me like all the pages which recently disappeared are the same ones that clk.about.com has recently started framing.
