If you visit the Twitter Web site, you'll see a refreshed bird logo waiting for you. Today the company unveiled a modified, sleeker (if you can call it that) version of it's iconic Twitter bird. The head feathers have been removed, and the bird now seems to be flying upwards instead of forward. It's also a darker shade of blue. We're guessing that if no one told you that the logo was new, that you probably wouldn't even notice the change. It's definitely different, but definitely subtle.
