I'm seeing a lot of sites now with a landing page that requires immediate registration or facebook connection to do anything. Are people seeing this as a successful way to get people registered, is it because there's not much to see other wise so they want you to register first?

Just seems like a terrible way to encourage registration, by making you "pay" in the form of a registration before really hooking you in.

I could be wrong, though. Would love to hear if other people have good or bad experiences with this type of flow.
