That's nice and all, but the benefit to "social login buttons" (or any oauth like system) is that it reduces the number of supposedly unique passwords your users have to remember. So they can use good passwords.

The username/password pattern is bad, and social login buttons, however much you think they mar your precious login page with confusing options, goes a long way to improving matters.

On the other hand, when their control freak CEO flipped out about 2 extra buttons, I wonder what they did with accounts that were already using the system. I guess send them a random password next time.

These are good UX lessons, so I'm glad to see the pointed out.

Actually, the biggest change I want MailChimp to make is to keep me signed in. I check that box every time, but they still want me to sign in again.

Also the login form wants me to login even if I already am. Seriously, if I just logged in, happen to revisit the home page, click the "log in" button in the top right, I am prompted to sign in again. It would be a far better experience to just take me into the admin panel like I requested.
