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.
If I interview someone and they grab the bill for lunch, I would need to specify this, as I would if I use an Amazon link that gets me 8 cents instead of an Amazon link that gets me 0 cents. If someone gives me a cool t-shirt with a logo and I wear it in a photo, ditto. Disclaimers all over.
This would be tedious for me and a continual eye sore for readers. But rules is rules.
To cover my ass and preserve your reading experience, please assume that, for every recommendation, link, and product I use, I may receive a small commission.
