When creating a username I was slightly thrown off by the inconsistency of calling it a 'username' versus a 'display name'. At first (w/o reading helptext) I thought clicking 'Create display name' was going to take me to another page to create a new name. Maybe think about going with one or the other, I would prefer username.
Also, when choosing a username there is no way to cancel the action and return to the main page (ie clicking off the dialog or maybe having a cancel button.)
That said, the signup process was really smooth and painless. Congrats!
Yeah, I was trying to add as many textual clues as possible to the fact that your Gmail username, etc. wouldn't ever be shown, but instead your "public" or "display" name. But, you're right, "display name" is inherently confusing.

That's actually intentional so that users can't post or comment without a username. But I should add helper text to explain that.
