Eric Spiegelman's Theory of The Internet: everyone has their own theory of the Internet.
Applies equally to advertising, monetization of content, the effects of Internet on public discourse and society and the kids, the role/demise of any media company founded prior to 2002.
My cousin Jim’s theory of the Internet: everything on the Internet is directly and exactly contradicted somewhere else on the Internet.
Assuming the truth of both of the above, if you add up every theory about the Internet expressed on the Internet it will equal zero.
