Online Bookmarking Sites provide web users with ability to save, organize and share bookmarks of web pages.
Bookmarking web-links is as old as Internet and has evolved over time.
As internet was evolving, we needed to save links. First, this ability to save links was provided in web browsers. Problem with this approach was that bookmarks were saved on PC. So, when you were working on any other PC, you did not have access to your bookmarks. Then came online bookmarking which was provided using web accounts and online toolbars (Examples Google toolbar and Yahoo toolbar). This solved the problem of accessibility. However, now people wanted to share their bookmarks with others. This was the problem solved by Social bookmarking sites. An online social bookmark manager allows users to store, organize (using tags), share and discover web bookmarks.
