Here's a way to test your Web savvy: Have you searched for the word Bebo?

On Google's annual top 10 list of the hottest search words and phrases, Bebo - an online social network that's popular in Britain and starting to gain traction in the United States - took the top spot, followed by MySpace, World Cup, Metacafe and Radioblog.

Each year, Google, the most popular search engine, releases an annual "zeitgeist" of the search terms that gained the most in usage in 2006, giving the world a peek behind its bare-bones home page and a window into the world's mind. This year, in addition to the predictable current events, celebrities and trends summing up 2006, Google's list seems to support the idea behind Time magazine's Person of the Year award, which was given to "You."

The top search terms are words related to user-generated content, such as blogs, social networking sites and podcasts.
