One of the complaints that we hear often from various publishers is the idea that, without copyright, other sites could simply copy all content.
In fact, this is the big complaint we keep hearing from newspapers these days -- the idea that they do all this expensive "reporting," and then along comes some "blog" that just copies the work, with a bit of commentary and gets all the traffic.
I tend to point out that this is a silly position to take. The thing is I say that even though I've experienced being on the "other" side of this discussion, and not with a smaller site, but a larger one.
