Google appears to be testing out a new service called Google Stars which aims to refresh bookmarks on the web.
It is a cloud based bookmarking tool that centralizes web content that you have starred through Google, be it web pages, images, web apps, Gmail messages and even map locations, and saves them in a library where you can access them later. The content saved on Stars would be automatically sorted into groups using built in filters or you can create your own folders. It also comes with a safety feature which archives spam and dead pages. And like all cloud services, you will be able to share your starred contents by making the folders public.
A Google watcher and Google+ user Florian Kiersch released the video below showing a preview of Google Stars at work.
