When you're exploring new career possibilities, eventually you reach the point where it's time to start getting an in-depth picture of the paths you are considering. Doing some internet research is a great way to start.
This site focuses on using the internet to research scholarly topics, but the ideas presented work equally well for researching careers. It's a good place to start if you aren't already practiced in the art of effectively finding the goldmine of information available out there (and it has some good ideas even if you are).
