Gawker posted an article that addresses the real cost of writing for free.
It's an interesting read, especially considering that many of us will do (or have already done) some freelance work.
What do you guys think- is their harm in working for free? What about unpaid internships or internships for "college credit" only? Do you think it's okay that young journalists sometimes have to put in their time with certain publications before officially getting put on the pay role? Where is the line between doing a little free freelance work and being exploited?
