People seemed to miss this article when it was posted here when it was published. Surprised at some of the comments; they seemed to only read the headline before commenting as well.

Like I said then, the social buttons didn't work for MailChimp because they implemented them after most users already had email logins. The article dismisses a concept that is integral to onboarding users at the beginning of your service. When everyone has been using their email login for years, why would they switch? I disagree with some of the people here saying these types wouldn't use a Facebook login. Lots of people use MailChimp; lots of people that have no issue using a Facebook login (and don't understand the risk in doing so).

This is a case of coming to the wrong conclusion with the wrong data.
