Whether Front-loading or end-loading registration requirements is more successful seems to hinge on which is greater: (1) the user's expectations coming into the site (2) how great the user finds the site once he's using it. If your site has a low value when the user signs up but this value builds as he uses it more (eg. networking sites) then you're probably better off front-loading the registration requirement. My experience.
