With commentary, here.
Last I checked, the vote was overwhelmingly in favor of moving it. I am not wild about this idea. It's not that I am wild about the current timing of the Eastern APA meeting. It is because of the large number of schools (something like 30% of American colleges & universities, as I understand it) who utilize the quarter system and for whom winter quarter begins immediately after new years.
Now, at my current institution, this would not conflict with classes. But I would really hate it if the E-APA conflicted with my first week of classes. I don't like canceling class, especially not the first week. And I would especially especially hate to cancel class the first week if I was also canceling class in order to do on-campus interviews a few weeks later.
It also seems to me that the fact that many universities begin their spring semester during the second and third weeks of January is a decisive reason not to hold the big meeting during those times. So I'm not sure why the fact that quarter schools begin during the first week wouldn't be decisive against that week, too.
