I concur - I really like the user experience with oAuth. As a user, you absolutely know that a) the service they're signing up for doesn't get their twitter credentials, b) they get more value out of the original service, c) they don't have to remember / make up / reuse yet another password. It's a lot like the paypal experience... Paypal handles all the "dangerous" stuff, like billing information; the user knows that it's paypal handling it, because it's on paypal's site; when they're done paying for it, they get redirected back to the merchant. It's a workflow many, many people are very, very comfortable with. It's a far sight easier to wrap your brain around than OpenID, that's for sure.
