@revelette2,
I don't decry the interwebs as a source for autodidacts--i'm just pointing out that it is a phony basis for claiming expertise in any subject. I often make pronouncements about history. I will go to Wikipedia to make sure of dates or the spelling of names. For factual content, though, i have learned not to trust that source. That's because i've read enough history to catch their errors, or the specious attempts at synthesis in their articles. I can almost always cite the sources for what i write. Many people here who comment on scientific matters are able to cite the literature.
Yes, you can learn a lot from web searches, and i heartily endorse using the resource. I'm not knocking google, i'm knocking those who use google and then come back here and pretend to have expert knowledge. Some people have accused me of that, too. However, apart from google new searches, you really can't use google or Wikipedia unless you are already well grounded in the subject in question.
