If you're a college student in a liberal arts program, chances are you enjoy writing. It's also likely that you're completely broke, but you don't want to go get some crappy job in a college town that thousands of other students like yourself are competing for.
That's why internet publishing is ideal for college students. You have lots to say, you're well educated, you can write, and you know what's cool.
So why not start a blog and throw Google Adsense on there? Get inspiration from other blogs and write a few posts. Enlist the help of your friends who may have specialized knowledge in certain areas, and get them to write a few posts for you, too.
Get a feel for the potential in internet publishing and see where you can go with it.
