facebook login is annoying but did get us out the door. poor grammar is intentional.
We used to have the words "WUT" repeated 200x in the app store copy, but Apple politely told us that wasn't good enough. We had more than a couple people tell us it was great though.
Do you plan to allow for a truly anonymous registration option that doesn't require anything beyond an email address (no facebook, no scanning my contacts, no phone number)? If so, when should I look for it because that's the feature that would make me try out WUT.
EDIT: posting too fast, so I'll just edit this post. I think you should edit your blog post with a disclaimer that you're a creator of WUT. It's not that I don't like reading about the products created by HN members (I like it a lot), but I (and I assume others) do want to know when the author has a vested interest in what he's writing about. The piece is interesting, thank you for writing and posting.
