In case you were wondering how to get a profile picture and make your profile personal around here. Use Gravatar.
What Is Gravatar?
An “avatar” is an image that represents you online—a little picture that appears next to your name when you interact with websites.
A Gravatar is a Globally Recognized Avatar. You upload it and create your profile just once, and then when you participate in any Gravatar-enabled site, your Gravatar image will automatically follow you there.
