Jerry - I believe what is more dangerous is the mistaken belief by many that whatever may be posted on the internet is true. The OP did notice that many sites seem to be "parroted" (we used to call it plagiarism) from one to another, and that the information was not necessarily true.
Seems some of the younger enthusiasts, that have grown up with the internet do not realize that there is a huge amount of data (called books) that is not now, and maybe never will be, posted to the internet.
As an example, my library of carburetor books takes up more than 250 linear feet of shelf space. Plus hundreds of rolls of microfilm, thousands of individual slides and aperture cards, a very large blueprint cabinet full of blueprints and drawings, etc.
Way less than 1 percent of this is posted, and may never be posted.
We old geezers have to help the youngsters learn how to find that which is not on the internet.
As far as the data on the internet, I have said since I first signed up that there is good news and bad news about the internet.
The good news is that anyone can post!
The bad news is that anyone can post!
I think the OP had the right idea; he found something amiss, and came here to ask about it.
Jon.
