I really didn't think it was of great importance to look in depth to see if all the sources on the internet were totally legit or not. I guess it makes sense if you are doing research since you would not just grab any book off the shelf in the library and extract whatever info without looking at the credentials of the author. I like to know that a book i use for research is not just a bunch of mindless dribble. I would have to say that I look for more than one site to see if there are simular pieces of information on different websites. Not that I do much research to be honest but when I do I would like to hope I am getting proper info when I retreive it online.
