Google is THE search engine for most people, so a look at their top worldwide searches from 2008 tells us what interests people:
1- Sarah Palin: really, people, #1 point of interest in the world?
2- Beijing 2008: okay it had its moments, but there were like 8 million hours of TV and coverage. It was harder to escape the Olympics then watch them.
3- Facebook login: Yes I like facebook. And i can get there without training wheels. Its url is facebook.com. How hard is it to find?
Also in the top ten: Obama, the Jonas Brothers, and tuenti (think Spanish facebook). Maybe now with Microsoft's Bing gaining ground, people will start to add some substance here.
And yes this comes from the guy whose top ten searches would include pizza and puppies. And Canadian politics. And searching for spoilers on Desperate Housewives. Ok, room to evolve.
