Why do some websites make it easier to register than to log in?
It seems like a fair number of websites will put a registration form on the front page of their website, but require a click to access the sign-in form. Why do websites do this? It saves users one click when they first sign up, but then wastes a click with every subsequent visit.
Fluther is one culprit. Netflix does the same thing. Twitter is a positive example, though: a site that puts the login form right up front.
Is there any logic to adding this wasted click? Does this supposedly lead to more registrations or something? Even if it does, is it worth the loss of efficiency for regular users?
