I'm honestly not sure what outcome he's asking for, though. This paper did capture the public imagination! He put it on arXiv.org (where it was accepted after their very minimal but non-zero peer review), and within days he was doing a whole bunch of press interviews.

What was he hoping to accomplish beyond that? Is this about getting another entry on the peer-reviewed publications list in his CV? The paper probably isn't worth that, at least as work in physics. But he's welcome to add a section to his CV about "public outreach" and talk about it there: he'd probably have a lot to say.
