"the default is: it belongs to you and you choose to exclusively publish your work on that website. Just because there's no license info doesn't mean it's public domain. You have the right to cite the content properly (meaning attribution) as part of anther work under fair use."

Interesting, thanks. (I presume there is jurisprudence to substantiate this statement)

If true, it opens up a way to question fair-use: Suppose Apple now properly cites JGuitar.com as the source, and otherwise continues its implementation unchanged, would that be fair-use? Hmmm.
