Did you think the description of Internet Marketing From The Real Experts was inaccurate? The cover indicates that each of the chapters/articles are "3 Minute Lessons", so the intention was to provide quick takeaways, which is why some were boiled down to bullet points.
It's a style of presenting information that pre-dates blogs. :)
With the exception of a small handful, the chapters/articles were 500 words or less each.
Affiliate marketing was the first topic listed on the cover for what was covered in the book.
