It really annoys me when I go to a site and the first thing I'm presented with is "login/create your account". I know nothing about your site, your product, your goals or what the purpose of this account is. Give me a demonstration of some kind or at the very least a paragraph about what it is you're doing before you ask me for my personal information.

Furthermore a lengthy FAQ does not supplant and introductory description/video.

Agree. What really annoys me most, are websites where you can only "login" using your Facebook account.

Anyway, in this case, even registering with your dummy/spam email address is worth the trouble :)
