Bing continues to expand its Social Sidebar features, today announcing that you’re now able to “Like” a friend’s comment or post that appears in a Bing search result, and comment directly to their Facebook post without leaving Bing:

Bing announced its Social Sidebar program in May of 2012, and has made steady progress in upgrading it since then, adding FourSquare, Quora, Klout (along with a Microsoft investment in the company, news authors, a new lighter look, and a previous iteration of updates to Facebook integration.  We’re not sure how much these investments are adding to Bing’s search market share, but it certainly is helping to differentiate the search engine from its competitors.

This comes just two days after Klout announced its new “Klout Experts” program, which will allow Klout users to offer themselves up to answer questions and have them surfaced on Bing:

Here’s a bit more from the Klout blog post:

Oftentimes, however, there are questions I have where the expertise to answer them lives beyond my personal network.

This is where Klout Experts will come to the rescue. The advice and answers you share through Klout will reach others at their exact time of need. Through our partnerships with Bing and others, people searching for help will be able to find your responses, then look at your Klout Moments to understand your perspective, and even connect with you on social media for follow-up conversations.

You can apply to become a Klout Expert by signing up on a waitlist.
