Bing announced today that it has redesigned the social sidebar, the third column of the three-column design it launched for its search results pages earlier this year.

“Today we’re rolling a new streamlined design for our social sidebar feature making it easier to find people who are relevant to your search based on what they’ve shared, publically blogged or tweeted about,” says Bing. “In a glance you can now see friends, experts and enthusiasts from leading networks including Facebook, Twitter, Foursquare and Klout have shared. While the sidebar will remain off to the right of search results – allowing you to decide when and how to interact with it – we’ve made some changes to the design.”

Users no longer have to hover over a friend or expert to see additional content. Bing will now show the content, marked as social results. They’ve also justified the results so there is less blank space on the page. Additionally, they’ve added a “+ see all” icon that lets you get more info.

On Monday, Bing launched a couple more information categories for the middle column – people and places.
