Reading John Baez's website reminded me that I hadn't checked out The n-Category Cafe for a while, so I added its RSS feed to Google Reader, to avoid that happening again.
Browsing through the articles, I found one that mentioned a short story by Greg Egan. I'm not sure whether it's new, or simply been re-published recently, but I figured I might as well point you to it, in any case.
The title is Steve Fever. You may need to click "skip intro" to see the article.
I've not read it yet, but according to John ... "It’s about an artificial intelligence so stupid it believes what it reads on the internet."
