I'm surprised that this has escaped my attention until now ... David Eggers now writes occasionally for the Guardian. In fact, after trolling through a search of the site, it appears to me that he has been doing this sort of thing since March of last year.

Three of his most recent "short short stories" include: The Battle Between The Giant Squid And The Bears Of Yosemite, And Built Like A Little Bodybuilder and True Story, Kansas City, 2003.
