What do digital footprints mean to you and why it is important to be considerate of what you leave behind in the digital space?

Communication via digital space requires the same level of awareness and professionalism as when writing a business letter. Web 2.0 emphasizes social networking and sharing of information, which is often contradicted by the public's concern for privacy and identity theft. I suppose that like old fashioned regular mail there will be web based scams and junk mail but that does not mean that protocol and ecorum needs to be thrown out the window.
