Recently, faces started to show up in my Gmail inbox.
I like this, because I can feel a real human connection with the human on the other end.
I'm starting to become conscious that my face is showing up in other's email. I believe this is happening because I keep a Google profile.
Another way to keep my face showing up consistently across the web is by maintaining a Gravatar.
Have you thought about how your face is showing up in other's inboxes?
How does this change email for you?
