Same here. The wizard mode seems broken. As soon as I rated more than a handful of movies it started showing 0 recomendations.

It seems that recommendations by the "wizard" mode are updated daily or so. I signed up yesterday and got nothing with the wizard mode. It starts to show promising results just now I checked.

You'd think that they wouldn't make it the default mode then. Or at least warn the user.

Regardless what the root cause is the end result is that it's broken from a user perspective.
