I am sure you have all heard about what happened to Cooks Source, the plagiarizing magazine with the clueless editor. No? Well, please, read up!: Copyright Infringement is for Dummies (a great links list of the train wreck compiled by the folks at Beyond the Veil).
As a would-be author, I have already seen my blog posts co-opted by false aggregator sites. They think they do me the favor by lifting the entire post... sure my name is there, and even a link, but if the entire text is pasted, why would a visitor come to me? It's dirty pool, but what the folks at Cooks Source did was so much worse. A print magazine! And really, would we even care if it weren't for the horrible attitude of the editor, Judith Griggs.

As I posted on their Facebook page (which will be gone soon, I'm sure, so hurry!) I have done plenty of work for free, both print and online--but always with a contract. Anything less is theft, plain and simple.
