Microsoft will close its file storage and sharing service Docs.com Dec. 15. As a result of its $26 billion acquisition of LinkedIn, Microsoft also got SlideShare, a more popular place for sharing presentations infographics and other materials with an audience of 70 million. SlideShare represents a better platform for storing and publishing Microsoft documents, the company said. Starting today, new users will no longer be able to create accounts on Docs.com, and by Aug. 1, users will no longer be able to publish or edit content. Docs.com was launched in 2010 in collaboration with Facebook.
