While I agree (mostly) with the conclusions of the article, the reason social login buttons exist, is that people want easy access to services without having to fill out a bunch of stuff. Services like social login, persona and other open id are a step in the right direction for solving that, but I think it would be best if it were implemented in the browser. Specify how you'd like to identify yourself to the web (or specific pages) and just add 1-click confirmations. Can't believe I'm saying this, but Microsoft's InfoCard would have been perfect for this :)
