I just found a useful answer on Amazon Askville and wanted to vote it up. It says you have to be signed in to vote, so ok, I’ll sign in. It’s Amazon, so I should already have an account, right? Not quite.

On the sign-in page, it says “Amazon Askville is an Amazon company that uses Amazon for credential verification”, and asks for a username and password. Looks like Amazon username and password would work, right? So I enter those, and it just says no. Then I click the create account button, and then there’s a link to sign in with Amazon credentials, so I enter the same Amazon username and password again and that works.

So to summarize: Askville’s initial signin page implies it uses Amazon credentials, but doesn’t, but actually does after 2 extra clicks which aren’t particularly intuitive.
