This blog is not primarily financially driven. If it were, I would have advertising and sell more stuff. That said, beginning December 1, 2009, the FTC requires bloggers to provide disclosures whenever there could be hidden interests or unspoken biases related to recommendations.
First, the obvious: I am a human being with strong opinions on the subjects I write about.
Second, also obvious: Feel free to write your own blog and share your opinions on subjects you care about.
