I ordered two for my two sons. They have both been on me to simplify my notes and tell them how I make a few of the crusts they like. Maybe I will write a couple of them in and leave blank pages for their results, trials, and variations.
For myself, even though it is not as well organized, I would only use (as I do) something I can use, search, edit, etc. on my iPad. I sometimes have things in 2-3 different places but I rely heavily on photos and screenshots. I like to think that someday I will get it all in one place. I was well on my way to that with a large number of recipes, mostly non-pizza but a couple things happened that have slowed me down. Microsoft products and I got a divorce quite a few years ago. Also, I don’t rely much on recipes for things that are not baked. Not always, but frequently not. In terms of software, I would be starting over at this point.
