Over the last three years, I have sent 12 emails to him, at the two addresses mentioned on the page (all were bug reports, as he says that's the only kind of email he accepts). Of these, 11 were processed in the way indicated on the page: several weeks later, I got a reply in my (postal) mailbox, with Knuth's replies in pencil over a printout of my email. For the other one, I got a two-line reply by email, saying thanks and that an updated version had been uploaded. (This was a correction to a section he was writing, that I sent immediately after a talk he gave about it. Interestingly, the "from" address on the email was that of his secretary—who comes in once a week AFAIK—but signed "-- Don".) So I think the content on this page is still substantially true, with rare exceptions.
