Weblog (or Blog)

I had a page about Markdown. It was about 15 or 20 screens of information with a comfortable layout with lots of whitespace. I thought it was a relatively complete description of Markdown. Now I find a McSparky book on Markdown that has 130 pages and 27 screencasts to discuss Markdown and how to use it. How do you write that much about a tool as simple and straight forward as Markdown? I don't know yet and haven't decided if I'll spend the $10 to find out. But it comes highly recommended. My curiosity may get the best of me. UPDATE 2019-04-29: After I bought my Macbook, I decided to buy the book. Most of it is about tools that you use Markdown with rather than Markdown itself. It's a good book, but the Markdown part is not worth the money; the other parts may be if you need that information.
