How do you keep tabs on your Internet Carbon Footprint, or digital footprint? How many do you actually have (I wonder if you know?!).

I try to keep mine to a minimum. I guess it is the norm now if you even go for a job interview they would probably have Googled you. I had a chat with my cousin who is all for the likes of Twitter and online details. He said its all about managing them to your advantage. In a way I agree.
