Bing.com/Twitter is live. Here's how it looks.
The "Hot Topics" tag cloud is at the top of the page, beneath the search box.
And here were the trending topics on Twitter at the time of the screenshot above. (No, Kanye West is not really dead.)
Below the tag cloud are tweets categorized by hot topic.
Now, let's take a look at search results. There's a Carolina Hurricanes game tonight, so let's see who's Tweeting about it. Notice the pause button at the top right of the results, which you can use to stop the real-time updating.
The sidebar on the left leads to Bing searches, not more Twitter searches.
