Social Media - Fearsome or Fantastic?

As a generation Xer who has never used twitter, facebook or created a blog, my first introduction to these concepts has been quite overwhelming.  While I realize these tools are widely used by individuals and organizations, I'm still waiting to be convinced that I must get on the band wagon.  Perhaps week 3 of my social media course will put me on the path of comfort in using these tools.  Until next week.
