> it's really cluttering the UI. It looks like Bing is trying not to clutter the UI with its social features by default: "Sidebar is the most novel component of the new Bing. It's a mellow, gray sidebar that is closed by default. It shows a thumbnail of your picture and two control icons, and that's it. There's a hint arrow to expand it. When you open Sidebar, it shows you stuff from social networks that's relevant to your search."
