The original book contains the blog as well as the collected rants: Approach.txt (about drain exploration), Paradigm.txt (the nature of life and informational reality), Realcrack.htm (reality cracking), Pestlock.txt (why pesticides suck) and Mol.html (thoughts on molecular genetics). There's also a couple of photos and diagrams.
The blog is also hosted here (and this is perhaps how the blog would have originally looked):
