The new conference eliteThe variety of stars at tech conferences used to be limited to bloggers, startup innovators, designers and programmers identifiable only after a glimpse at a name badge. But a new class of celeb is rising with more recognizable star power: videobloggers, often good-looking and engaging, practiced at being entertaining, and a prime target for conference-long entourages. Other techies love hooking up with a less nerdy brand of internet celeb. At this weekend's South by Southwest conference, star vloggers included Casey and Rudy from sci-fi show Galacticast and ABC News vlogger Amanda Congdon. The biggest star by far, though, was Ze Frank, host of the one-man "The Show," who cruised a few parties, hosted the annual Web Awards, and performed a Powerpoint stand-up routine at a Buzzfeed party. Prediction: "Fun" conferences (full of the geeks who do the actual work of Web 2.0) like SXSW will have more vlogger presence than "business" conferences like the upcoming suit-heavy Video on the Net.
