Social bookmarking allows internet users to store, organize, search, and share bookmarks of web pages through online services. Popular social bookmarking sites include StumbleUpon, Delicious, Reddit, and Digg. The key advantages are that bookmarks can be accessed from anywhere through these online services, and users can discover new pages through browsing tags and ratings added by other users. However, there is a risk of spam if sites generate fake positive ratings to appear more popular than they are. Social bookmarking is also related to social networking, as some sites allow linking to other social profiles.
