We've never quite figured out what Jeremy Johnstone does, besides critique other people's code, take bad pictures, and trade barbs with gossip blogs. Whatever his official job is, he apparently requires seven computer screens to do it. (In fact, Johnstone has so many screens that they couldn't fit in one photo.)

Memo to Yahoo CEO Carol Bartz: You could save a few thousand bucks, easy, by redistributing five of these screens to Johnstone's colleagues instead of buying new ones.

Johnstone, who fancies himself quite the lensman, has somehow become Yahoo's house photographer. He's been posting his corporate work, without authorization, to his personal Flickr stream.

In his self-appointed role, Johnstone, unbelievably, managed to take a publicity shot of Yahoo TechTicker star Sarah Lacy that made the photogenic valley fox look bad. The online-video show's producer, who never wanted to go with Johnstone in the first place, had the photos reshot — and was furious to hear that Johnstone had published the unapproved photos on Flickr. Johnstone took them down after a late-night call Friday — which was the first he heard, we understand, that his original photos hadn't made the cut. He's being replaced by a real photographer. If only more of the amateurs at Yahoos were meeting his fate.
