When is Yahoo better than Google?

Here's a tip for communications professionals.

Most people in the UK use Google. However, it isn't always better.

For example, try to judge the authority of President-elect Obama's transition website, change.gov. Put link:change.gov into Google and you get 0 results. Put it into Yahoo and you get 1453 results.

The more comprehensive Yahoo database is more useful for PR, marketing and comms people. Perhaps another good reason for the halt called to negotiations between the two search engines?
