This was a huge request on our app as well, we did it, and about 10% of our users are email sign-up.

On the flip side, when/if you do decide to go with email sign-up, be prepared that users who once signed-in with their social media account will start signing in with their email address and expecting it to work, even though they never showed a password.

It seems to me users use the same social media service to sign into most services, so they don't get confused between facebook or google login buttons, but give them an email field, and they get confused as to how they have been signing in in the past.

Anyone else seen similar behavior? Or is it just us?

We're venturing a bit off topic here, but yes I can understand a user with many logins on many sites may not remember which they used on yours. You can't really remind them on failed login without subjecting yourself to leaking that a user is a member of your service (or full blown user enumeration attacks).

In these cases where social logins are the primary approach most users use, I suggest making the email login look like a social login button, but make it clear it's email (i.e. more than just an icon) and trust only the few I-never-use-social-login users will leverage it while not confusing the others.

This is great advice, thank you!

That's exactly why we steered clear of adding email sign-ups in addition to our social auth. When we had both, it caused a lot of confusion, especially given the small percentage of sign-ups via email.
