You know Linux isn't just a hobby anymore when it starts having trade shows with giant rotating signs and booth bunnies. Linuxworld Expo, at the Moscone Center in San Francisco, is such a show - even more so since moving from the much smaller venues of Santa Clara and San Jose. Guess I'll take the train up there again this year, and see what marvels are on offer, even if they are mostly aimed at Corporateland.
