And when I do a regular Bing search for, say, "ac milan," I'm not getting any real-time information, twitter-based or otherwise. Going to bing.com/twitter doesn't seem to be an improvement over just going to twitter.com to run my real-time search.

Searching "ac milan" on Google does at least bring up their last Serie A result and a news story about how they came from behind to beat Madrid this afternoon. I'm pretty sure Google will find a good way to integrate real-time tweets and status updates into its regular search results.
