What I try to do is make the point logically then provide links to supporting documentation. I don't link to blogs and a link is not my whole post. They are not mutually exclusive. One can use logic and reason AND provide links.
What's wrong with blogs ?
Blogs are opinions, usually not by people who are any kind of authority ion the field they are blogging about. Many people use blogs as support for their arguments and that's fine, I just won't.
Theorists are also just people with educated opinions.
I was mostly just being jokey since I am a blogger
