I'm attending SXSW Interactive for the first time and could use some tips on how to get the most out of the conference.<p>I would like to make good business contacts, but I'm not that good at power schmoozing (which I find to be pretty transparent, anyway.)<p>I also like to observe excellent speakers, even if the topic isn't immediately relevant to software development. I see some big names like Tim O'Reilly, Jason Calacanis and Guy Kawasaki on the agenda. Are there any "can't miss" sessions, possibly by lesser-known but still excellent speakers?
