A link to 7 ways to write a short ebook fast

Ran across a very interesting article:
http://writenonfictionnow.com/seven-ways-to-write-or-blog-a-short-ebook-fast/

It says there are 7 types of short ebooks:

1. Tip book featuring a list of 10-101 tips, usually one per page. I wonder if I could create such a thing in crochet, ways to hold your hook and yarn, basic crochet stitches and designing your own patterns. how to not lose count of your stitches - still haven't found a good way with that. Though ripple pattern works good because can check stitches by appearance.
2. List book where you list and item and write a short essay of the item on your list.
3. Quotation books or 25-50 quotes, then elaborate on what you think they mean, what they mean to you, why you chose them and how your customers/clients can use them to further themselves or business. Just researched this. Most quotes are on pinInterest. Also found crochet poems.
4. Rx (prescriptive) nonfiction: offer guideance or direction on a particular topic. e.g. handbook, guide, rule, step....
5. Anthology; content solicited from other experts. Specific topic, word count, deadline, and a request for rights to publish their work in your book. then add your own introduction, chapter, and conclusion.
6. One Big Idea explained then explored using anecdotes, case studies, reports, statistics, other evidence. I wonder how many people and what age groups crochet? Where can I find this info? Do people who crochet also do other crafts? Why crochet?
7. Q&A book where common questions are answered by you. What typical questions are asked by crocheters? about plarn?

side note:  So far am accomplishing goal of free writing everyday even on the weekend where I don't have time of my own. Need to quick write a post on crochet increasing which is due today. I figure as I learn more I can always go back to the posts and add more.
