Daily Show correspondent turned Apple pitchman John Hodgman is on Twitter, and he's using it to mock the habits of Twitter users. His salvos include entries like " BATTLESTAR GALACTICA REFERENCE," "VAGUE SHOUTOUT ('Cheers, @SFslim!')" and "GRADE A NON-SEQUITIR." Normally, this would be a bad self-promotional strategy. But as you can see from this complicated (and very scientific) Venn diagram which illustrates the interlocking audiences gripped by Hodg-mania, all Twitter users already fall into fan bases generated by other media channels, so Hodgman can abuse them at will. Except, of course, for hobos. Never, ever mock hobos if you know what's good for you.
