John Battelle's finger photoDan Fost at the San Francisco Chronicle at last discovers the provenance of this legendary pic of Federated Media's John Battelle. Turns out that the photo originally emanated — like so much in tech news — from the machinations of John Dvorak. It dates from Battelle's Industry Standard days, taken by Dvorak during one of Battelle's infamous "money-wasting Friday parties." Dvorak photoshopped the pic to look like black-and-white film, gave it the Register, and presto: net artifact for the ages.
