I agree with you to a point.
I agree that "Attributes and references are a good thing."
I also agree that some of us, myself included, should do a better job of supporting our assertions with references.
However I disagree that the earth sciences should be held to a different standard than all others. Namely that every basic principle in earth science should require a reference to some, many, or all freshman college texts in geology when this is clearly not required by any other field.
I believe that you have indeed read the basic principles of geology somewhere else, most likely in your own studies. However, I also believe The Matt is completely innocent of any plagiarism, he is simply stating basic concepts in simple terms. If Coragyps mentions ionic bonding, is he required to cite a freshman chemistry book? If Cavediver mentions the general theory of relativity, is he required to cite a freshman astrophysics book? Do we really need a citation to freshman biology texts every time someone mentions natural selection?
Or would they be accused of plagiarism for not citing the source?
I mean come on, I can recite the basic laws of geology, I bet you can, and I bet The Matt can, all from memory alone. I think any accusation of plagiarism is uncalled for.
I also believe, as I assume you do, that further discussion of this topic should be relegated to a PNT, so as not to clutter this thread.
