Professional Social Bookmarking Services -

What is social bookmarking:

Social bookmarking is a method for Internet users to store, organize, search, and manage bookmarks of web pages on the Internet with the help of metadata.
In a social bookmarking system, users save links to web pages that they want to remember and/or share. These bookmarks are usually public, and can be saved privately, shared only with specified people or groups, shared only inside certain networks, or another combination of public and private domains. The allowed people can usually view these bookmarks chronologically, by category or tags, or via a search engine.
Social bookmarking services let you keep links to your favorite web destinations in one location that's accessible from any computer on the net. Add the ability to share your favorite web destinations and search through other users' bookmarks to discover new sites, and you've got a highly addictive and truly remarkable phenomenon
Fact about social bookmarking;- The reason that social bookmarking has exploded in the last year is obvious -- storing your bookmarks online instead of in the browser just makes sense.

ADVANTAGES:-

• All tag-based classification of Internet resources (such as web sites) is done by human beings, who understand the content of the resource, as opposed to software, which algorithmically attempts to determine the meaning of a resource. This provides for semantically classified tags, which are hard to find with contemporary search engines.
• Additionally, as people bookmark resources that they find useful, resources that are of more use are bookmarked by more users. Thus, such a system will "rank" a resource based on its perceived utility.

DISADVANTAGES:-

• No standard set of keywords (also known as controlled vocabulary),
• No standard for the structure of such tags (e.g. singular vs. plural, capitalization, etc.),
• mistagging due to spelling errors,
• tags that can have more than one meaning, unclear tags due to synonym/antonym confusion,
•  highly unorthodox and "personalized" tag schemas from some users, and no mechanism for users to indicate hierarchical relationships between tags
• Services which allow both tags and folders for organizing bookmarks (such as Netvouz) make this less of a problem though.
• Social bookmarking can also be susceptible to corruption and collusion
• Due to its popularity, some users have started considering it as a tool to use along with Search engine optimization to make their website more visible. Spammers have started bookmarking the same web page multiple times and/or tagging each page of their web site using a lot of popular tags, hence obliging the developers to constantly adjust their security system to overcome abuses.
• Because of this, some social bookmarking websites were forced to add CAPTCHA protection against spam, which caused some problems for people who use social bookmarking for non-spamming purposes.
