What do I hope to learn from CPL 2.0?

I hope to become more knowledgeable about the social networking capabilities of the Internet and not to feel like such a dummy when my very tech-savvy son and husband are throwing around terminology. Frankly, I want to impress my 20 year-old son with what his grey-haired librarian mother knows about the modern world! I also want to use my new knowledge to assist library customers and the staff at my branch who might be even newer to technology than I am.
