Google Hot Trends

Google Hot Trends page is worth an occassional glance, just to see what keywords are buzzing. It does seem a little strange to me that 'Prince Valiants Wife' came in number 10, while 'Lost Finale' came in 11? I'd be curious to see trending over time to get insight into business opportunities... Another question is why is last nights American Idol winner, Jordin Sparks, #73? There is something about Hot Trends I don't understand yet.
