Most social bookmark services encourage users to organize their bookmarks with informal tags instead of the traditional browser-based system of folders,
As these services have matured and grown more popular, they have added extra features such as ratings and comments on bookmarks, the ability to import and export bookmarks from browsers,
The concept of shared online bookmarks dates back to April 1996 with the launch of itList,[2] which had public and private bookmarks and other features.[3]
