Stopped by the Yahoo! Buzz Index – Buzz Log for the first time in a while today. Biggest breakout new idea? Hoodia. I had no idea.

The index is organized primarily around actors and media, which is pretty trivial stuff, easily explained. I’m far more interested in the larger trends, the stuff that represents what people are paying attention to that might actually have a half life.

So what’s the most interesting takeaway? For me, it’s that the stuff that changes the most is banal. The teen star of the moment and the sports team of yesterday. People don’t like big changes but they obsess about the little ones.

PS according to the BBC, all those Hoodia ads you see online are frauds. They don’t have real Hoodia in them. Just thought you’d want to know.
