new media and what young people should know...

As I am looking at entry level Public Relations jobs, I feel confident and weary about my experience and skills with new media. I am textbook confident, in that I know what it is and how it should be used. I even have some experience using it. But I am weary to advertise it as a skill I possess when applying for a job. There is so much about blogging that I don't know and I have no clue how much my potential employers may know.

I am by no means an expert, but I know enough to start learning.
