What’s the opposite of spring cleaning? Spring adding? Spring enhancing? Whatever it is, Bing is doing it, with an announcement last week of new features coming up on its Web site.

The first thing is the Quick Tabs in the Explore Pane at the left of the search results. The links here are sort of a combination of clustered search and context. If you do a search for Dallas, for example, you’ll get general links to Dallas events and Dallas weather and Dallas jobs, but you’ll also see related searches like Dallas TV Show, Dallas Morning News, etc. Bing is testing moving some of this data to the top of the page for better/faster/more obvious access. I’m not seeing this yet, but I hope the results are true tabs (easy to get back to original results.) Bing is doing a good job of helping users easily add context to their searches and get key data from their searches with their left nav.

Bing is also riding that real-time bandwagon. It’s already teamed with Twitter and has started testing “new experiences for real-time results.” Also in its own words: “For example, when you search for a publication such as the New York Times, Bing not only gives you quick access to specific sections of the destination website, but also provides the most popular shared links from that publication.” When I did a search for New York Times I got a first result that looked like this:

In this case the latest links at the bottom were not, as far as I could tell, the most popular. Instead they were the latest items from the NYT feed. The “Latest Posts” feed links to an XML file. Searching for Washington Post and LA Times didn’t find any latest posts. However, searching for Dallas Morning News did find a search result for the latest stories.

From Bing Cool to Bing Pfui. Bing also announced a new feature called Map App. Map App shows real-time data from foursquare on the map you specify. Sounds neat, right? I’ll have to take Bing’s word for it; I can’t get it to run. I’ll hold off on my rant about Adobe Flash and now Microsoft Silverlight… gaaaaah.

The map app aside, I’m looking forward to integration of more shortcuts to important data in search results, and, hopefully, some more credible real-time than a random Twitter stream.
