You don't hear raps about Guy Kawasaki and Google+ very often, but this one, which has a pretty hot beat, I might add, fills that void. It gives a nice, brief recap of day one of SXSWi in a way that's entertaining and easy to digest.
There's plenty going on that the recap didn't touch on. The event is just too big, that I don't believe any one report or even publication could capture all of it, but everybody has their highlights. No pun intended.
Perhaps we'll see some social discovery-based freestyling before the event is over. That's clearly one of the big trends in Austin this year.
