Bing has been tweaking its search results interface for the past week or so. First, they added people and places information to the middle column (Snapshot). After that, they launched a redesign of the social sidebar.

Today, Bing has updated its Safari for iPad (and iPad Mini) browser support with the new social sidebar.

“In a glance you can now see what friends, experts and enthusiasts have shared on leading networks including Facebook, Twitter, Foursquare and Klout related to what you’re searching for,” says Bing Social principal group program manager Chris Rayner.

The design will adapt to landscape or portrait. Support will be rolling out over the next few days.

Microsoft also expanded Bing for Desktop to more versions of Windows and more languages this week.
