To be honest, I was going to blow this one off for two reasons:
One, because the results have been so varied that it's become a matter of parody;
And two, because I didn't think I'd produced a body of work with any degree of consistency in recent years. Certainly, I haven't cranked out any fiction in a long while.
I changed my mind for two reasons:
One, because leonard_arlotte reported remarkably consistent results from his LiveJournal entries;
And two, because I realized that my comics blog was a deliberate attempt to maintain a consisten "voice" throughout its long-form entries.
Out of ten long-form entries, I got the following results:
One J. D. Salinger:
Four H. P. Lovecraft:
And five David Foster Wallace:
...to which I can only echo leonard_arlotte's reaction: who?
Illiterate Philistine that I am, I've never read Salinger. The Lovecraft results, however, did not surprise me in the least; like HPL, I have a penchant for purple prose, archaic adjectives, and gratuitous grandiloquence. I suspect that if the algorithm were keyed to identify italics, my writing would have shown even more kinship to that of Unca Howard. One of the HPL-tagged episodes did, in fact, have several FULLY CAPITALIZED PASSAGES, though that was more in emulation of Jack "King" Kirby; I rather doubt that the meme-encoders included his Groovily Bombastic Scriptage in their algorithms.
Were I in a more frivolous mood, and had more respect for the underlying algorithms of random internettery, I might dig out some of my college papers (aside from the one that got repurposed as a KDDR entry) and see how they test out; even when I'm writing serious technical discourse, my florid style often bleeds through, and I can never resist a good chain of alliteration.
For the record, I analyzed this post, and got H.P. Lovecraft again. Given that I found myself deliberately emphasizing the Lovecraftian tendencies of my style as I wrote, that's not only unsurprising, but quite probably biased: "gaming the game", as it were. So, grains of salt all around, and 'ware your blood pressure, all and sundry.
If the meme-writers had my sense of humor, any text that referenced the "I Write Like" page itself would be weighted toward Douglas Hofstadter.
