Gnomedex report from PBS' Mark Glaser

SEATTLE -- I am here attending the geekfest of geekfests called Gnomedex. Its name is a play on the old tech conference Comdex, which ironically doesn't exist anymore. Coming here is a throwback to my time as a pure tech journalist going to conferences such as Macworld and the Consumer Electronics Show. But what's interesting is that even in the geekiest settings, and perhaps especially in the geekiest settings, social media has come to the fore.
