This one from Dean Wesley Smith is worth a read. It's about not getting ripped off, which obviously is a topic close to my heart.
My favorite quote?
...electronic publishing is scary simple.
Does it take a learning curve? Yes. But so does Angry Birds. Actually, I think Angry Birds is harder to learn than electronic publishing.
I think he's probably right.
There's also a good comparison of the costs of e-publishing and traditional publishing. I know some people believe it when publishers tell them that e-books cost just as much to make as paper books. I assume they also believe it when guys tell them that ejaculate prevents wrinkles and is really good for the skin of the face.
