Looking at the graph of the top three Movers, I'm reminded of how my job in Web metrics has made me (slightly) cooler. There was honestly a time when I had no idea what March Madness was--none at all. I think I occasionally heard it and associated it with springlike things: allergies and short pants.
One glance at this graph (or the previous years' versions of it), and I see two things: something big is happening related to sports; the sport in question is pretty below the radar until March. After one click-through to the sites currently experiencing huge gains in traffic, pretty much anyone who was always picked last for teams in gym class can sigh and say, "Ah, yes, college basketball championship."
Thank you, Alexa, for giving me a clue about the rest of America's obsessions.
