Parse (YC S11) adds User Accounts to Android.

Just to be clear, these are User Accounts for apps built for Android using Parse, akin to iOS's single sign-in using Twitter?<p>I was anticipating someone had built multiple user logins for Android devices, which would've also been fascinating.

It would be cool if there were custom support for linking accounts, such as with facebook. That code is never fun to write, but common.

Somewhat off topic:<p>This page has a beautiful javascript effect if you scroll. The index follows the page smoothly and highlights the displayed section. Does anyone know if this is a public library/function?

I wish the title would've meant the solution to the Android tablet multiuser problem¹ as well.<p>¹: <a href="http://code.google.com/p/android/issues/detail?id=15030" rel="nofollow">http://code.google.com/p/android/issues/detail?id=15030</a>

Hey we were just about to blog about this but you beat us to it! We also have some other good stuff we're set to announce this week so keep an eye out.

what's the business model here?

I sure hope this ties into Android's existing account management APIs. The one that already provides push notification support, automatic controllable data synchronization, etc.<p>Wow, not even 10 seconds and it's been shot at. What am I missing here?
