Typical that the paper quotes Chris as, Chris Collyer, and Hob in inverted commas as 'Hob' - as if using a pseudonym is not quite 'acceptable'. Same sort of academic snobbery exists on Britarch where anyone wishing to post anonymously is consider somehow outside the accepted order of things. TMA, and similar forums, are a font of information, knowledge and experience; why else would people from the 'academic' community be 'lurking' in the background ;-)
