New York - Facebook plans to start offering a form of notepad function, so users can store internet links and posts about moviesand music in one place for viewing later.
The stored data is only viewable by the user, but can be shared with friends, Facebook reports.
Similar storage services are already offered by sites like Instapaper, Pocket and Evernote, as well as by restaurant review sites like Foursquare and Yelp.
Facebook seems to hope that users will warm to the new function, binding them ever closer to the Facebook universe and making them more loyal Facebook users.
However, there are no guarantees. Facebook has had flops with new services before, as with its Home interface for Android smartphones.
