Bing brings out the tweets | Webware - CNET
Bing will now surface results for certain celebrities (leading to the odd pairing of search guru Danny Sullivan and American Idol host Ryan Seacrest in the same sentence) when users search on their names and "twitter," the company announced Wednesday afternoon. It's not indexing all of Twitter, instead picking "a few thousand people to start" and using Twitter's public API to display those results in a special box among the other search results, such as stories that a person might have written about Twitter.

Hmmm... might take another look at Bing.
