I felt compelled to respond to "I don't like mercenary bloggers"

I have one of the clearest disclosure policies possible about everything I write, and very little is specific to topics like "making money online"

A lot of the topics covered are similar to more mercenary sites, but I believe the depth of the content and attention to detail is a key differentiating factor.

I love to study the effect of different things. As an example I know that just a single negative review on Stumbleupon can effectively kill the possibility of my articles from being appreciated by others.
