The internet and blogging is all about the concept of you. Who you are. What you like. What you dislike. What you do. What you eat. What you drink. Where you go. Who you love.
Sites like twitter and facebook have taken the concept of being able to instantly communicate the concept of you instantly to a mass audience. Perhaps the greatest example of this is the video-posting site YouTube where you can upload movies featuring you in all of your glory.
Some have even gone so far as to call today's generation of bloggers, the You Generation — or the tech and internet savvy offspring of the eighties me decade.
