Readings about "digital citizenship"

I am compiling two annotated reading lists for young adults on the following themes: digital citizenship and career and identity exploration. This is for a course I am taking this semester about assisting the struggling adolescent reader.

I am looking for a variety of high-interest texts to add to both lists. The definition for "text" here is quite liberal. I can use traditional print resources such as novels, nonfiction books, articles, poems, and song lyrics, but I am also interested in electronic and interactive resources like web sites, games, film, television, etc.

Any suggestions for materials that might engage reluctant readers and stimulate discussion would be greatly appreciated.

Regarding the first theme, I am looking for texts that explore the issues, opportunities, challenges, and responsibilities of growing up in a digital world.

For the second theme about career/identity exploration I need culturally relevant resources that engage young people in thinking about this question: "What in the world am I going to do with the rest of my life?"
