I wanted to quibble with one thing Prof Smith wrote.
You can, for the moment, freely download these draft 16 chapters. However
The deal is that — if you actually read them — you send any comments you have, however brief or general, to comments at godelbook dot net1.
I note — not entirely with surprise but with disappointment — that for the last versions, the ratio of downloaders to those who’ve sent comments seems to be well over 200 to 1. OK, no doubt a good many download in a speculativve way, and find that the book isn’t for them. Still, if that ratio doesn’t improve a bit, I guess I’ll go back to just circulating my friends and relations! :-)))
My ratio of readers to commentators is frequently in the 1000 to 1 range. This kind of thing isn’t unusual. If you really want comments, you should send manuscripts to friends with begs for comments and post things online. I think from the smileys Prof Smith knows this, but I thought it worth pointing out that his situation is not particularly unusual.
1 I’ve replaced a live email link here with a description of the email address because I’m a little afraid this page is scanned regularly by robots looking for spammail addresses, and I thought I’d spare Prof. Smith that pain.
