Yoda contributes: It was published before his interview and he was quite nervous, because he was afraid that the interviewer would have read it and consider him to be too frivolous

As I remember it, he had asked that the article on thiotimoline be published under a pseudonym but the publishers messed up and published it under his real name.

Good memory on the details, Yoda. See my link to Only a Trillion, above (or below depending on whether you are a flatliner or a threadnodist) for the source.
