There is a very enlightening article in today's Wall Street Journal on how fewer teens are seeking employment and the impact that is having on the broader U.S. economy.
My 16 year old nephew started a summer internship with us a week ago. I'm blown away by how much energy this kid has. He's written 3 guides on how to install LineBuzz on various blogging platforms (see wiki.linebuzz.com).
I haven't seen many teen interns in the software industry. Sure it takes a few years to become a programmer, but I think high energy and a strong desire to learn and prove themselves makes teens a great and underutilized resource.
