Advice for new folks: Complete your profile info -- at least your name, ideally some bio info and avatar -- before you import your contacts to start following people on here.

The notification a person gets when you follow them is the salient moment to be followed back. But I'm getting notifications of new followers where I just see a handle I don't recognize and the default elephant. I'm sure some of those are people I know and would follow back if I realized who they were.
