Twitter API lead Alex Payne announced today that Twitter is now accepting applications to its OAuth private beta, making good on the promises he made on the Twitter API mailing list and had repeated on the January 8 Citizen Garden podcast (transcript by stilist).
It’s worth pointing out that this has been a long time coming and is welcome news, especially following Alex’s announcement to limit Twitter API requests to 20000/hr per IP.
It does, however, provide a way for Twitter to better track the use of its API, and to enable higher quality of service for trusted (paying?) applications and to surface them through a Facebook-like application directory. It also means that Twitter users will have finer grained control over which applications have ongoing access to their accounts — and will be able to disable applications without changing their password.
I’m on the beta list, so I’m looking forward to seeing what their current UI looks like — and what lessons we can extract for other services going from zero OAuth to a completeld delegated authentication model.
