First social login is nice for a user, I also don't care enough about the app to sign up, have to remember what username plus another password (or more realistically, generate another password with lastpass, but oh your site doesn't like 80 character alphanumeric logins because you don't like the ampersand or you've limited it to 32 characters or whatever I've lost interest) maybe i need to verify the email to complete the login or something I don't know I've wandered off. Now it's not that I don't want them to know who I am, I'm ok when them knowing my email, I just don't trust them not too post on my wall or subscribe me to notifications or whatever (this is why the google social login is IMO nicer because you can clearly switch a box to make it not visible to anyone but you) Secondly as a developer social login is nice because A) users like it (see above) and B) you off load much of the work of having to deal with authentication and authorization.
