Most social bookmarking sites organize tagged items. Users can browse based on popularity, topic, politics, news, tech, sports, and more. You can save websites and send the link to your friends.
BookmarkGroups enable users to collaboratively underline, highlight, and annotate an electronic text, in addition to providing a mechanism to write additional comments on the margins of the electronic document. BookmarkGroups is an online service, which allows users to add, annotate, edit, and share bookmarks of web documents.
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, emailing of bookmarks, web annotation, and groups or other social network features.
BookmarkGroups is especially useful for creating a list of resources, for example, for academic purposes or simply for sharing with other people who share the same interests as the user. BookmarkGroups can save a new bookmark on your desktop, and then access it later from your phone or tablet. Sign into your account from any device and you will find everything you added and updated.
