Hmmm Found this text book in a home schooling catalogue - Using the Media: Fact, Fiction, and Opinion. The print edition describes it like this:

Enhance students' ability to distinguish between fact, fiction, and opinion in the media. Engaging activities sharpen students' critical thinking skills as they decide whether statements made in the context of various readings found in the media are factual or merely opinions. Media sources include newspapers, television, and the internet.

Sounds like a primer for young bloggers.
