I got my book yesterday (arrived at the local bookstore) and logged on last night, but I realized I should read the first couple of chapters before really getting into it, so I got in bed and started reading. It reminded me of a few online college courses I took. A *lot* of comments by other students - like hundreds - but at least (unlike my college classes) you didn't have to click each one separately and wait forever & ever for it to load.
I think I'm going to love it.
I admit though, I did feel stressed out for a minute and then I realized that I'm under no pressure, it's not for credit, I'm doing it because I want to simplify my life, not because I need to for work, or to get a good grade (A+!) or any other reason except because I feel like it. So that took a little of the weirdness away. I think it's going to be wonderful.
