Facebook is acknowledging that most smartphone owners want a broader view of the social-networking universe, not just a window to planet Facebook. Starting Thursday, the company is incorporating Flickr, Pinterest, Tumblr, and Instagram content into the Facebook Home lock screen experience, marking the biggest modification since a dramatic shift in strategy that came after its once-bundled Android software package failed to move consumers. The Home improvement, only available in the Facebook for Android beta application to start, gives application users the option to add streams of content from the third-party, image-rich social services to their smartphone lock screens. The release turns Cover Feed, a picture-centric, panning version of News Feed that replaces a smartphone’s lock screen, into a more socially aware zone where people can consume photos and posts from places other than Facebook.
