If you’re on Twitter, you’ve
no doubt seen some very interesting avatars. Some people use logos, or images to represent themselves, their company and/or brand. Most people use photos of themselves to help build that know-like-trust factor and personalize their social networking experience.
One thing you will also notice is that people will change their avatar and add things to it. Sometimes it’s just a decoration for a particular holiday. @MariSmith is one that comes to mind, as she will add a red Santa hat to her Twitter avatar. She changes her avatar frequently to reflect her mood, or for an upcoming event.
