It turns out there's already a Dreamwidth version - https://whatwasthatbook.dreamwidth.org/ - though I don't have any connection to that, and it doesn't seem to be very active, though there's some recent posting.
If anyone wants to start a new WWTB-type community over there, I'm happy to point people to it. Just leave a comment on this entry.
In the meantime, I'll leave these archives up for people to search.
(The sticky post in this community has a link to the new WWTB-style Dreamwidth community. If you are looking for a book, go there!)
