Could this be the world's most awkward photograph? On the left, Brad Fitzpatrick, founder of Livejournal, the online diary site, and still a key exec at the company that bought him out, San Francisco's Six Apart. Also at last night's party in San Francisco's South of Market district, on the right of the snap, Artur Bergman, a colleague who had a widely-known affair with Fitzpatrick's wife. Correction: former colleague, and former wife.
