BitTorrent founder Bram Cohen has Asperger's syndrome, a sort of autism lite thought to be common among geeks, BusinessWeek tells us again and again and again . But does he, really? Midway through the article, the writer admits that this fact was too good to check: "Cohen never sought a formal diagnosis." True, Cohen is obnoxious. His coworkers at the file-sharing startup have learned to put up with behavior he attributes to Asperger's — aimless, unchecked nattering and an utter lack of tact. But did anyone stop to ask if he was simply clueless and rude — or, quite possibly, given the violent ravings he once published on the Web , mentally ill? (Hey, Cohen is the one who started tossing around unproved diagnoses.) That's not the only question about Cohen the article left unanswered.We would have asked what, precisely, Cohen does at the company, and why its investors still allow him to visit the office and waste employees' time. If the answer is that they feel sorry for a guy who claims to have a mental condition, but has never even tried to have it diagnosed, then you'll have a sense for their abilities to perform due diligence. BitTorrent recently went through a round of layoffs. Its attempt to sell movies online has failed; its attempt to use file-sharing technologies to serve as a content-distribution network, which speeds up downloads for paying customers, is likewise faltering, as BitTorrent find itself overmatched by much larger, more professional competitors like Akamai Technologies. Cohen may well have Asperger's. He created an interesting technology in BitTorrent. But neither fact entitles him to keep drawing a paycheck from the company he founded.
