Interesting book, there are some blasts from the past there for sure. "Atomic Cinnacide"...that stuff was discontinued a year ago.Most of those recipes have been floating around Reddit for awhile, but it's nice to have so many of them compiled into one doc. Would have liked to have seen something like a "best of the best recipes from DIYers", since I'm more interested in what other DIYers are doing than what's already been done by for profit companies, but I can find that stuff myself. Not much really earth shattering info beyond that, though I'd undoubtedly have appreciated it more if I'd had it when I was just beginning DIY, but it's all good just the same.
