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.

Most social bookmark services encourage users to organize their bookmarks with informal tags instead of the traditional browser-based system of folders, although some services feature categories/folders or a combination of folders and tags. They also enable viewing bookmarks associated with a chosen tag, and include information about the number of users who have bookmarked them. Some social bookmarking services also draw inferences from the relationship of tags to create clusters of tags or bookmarks.
Many social bookmarking services provide web feeds for their lists of bookmarks, including lists organized by tags. This allows subscribers to become aware of new bookmarks as they are saved, shared, and tagged by other users.
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.
Advantages
With regard to creating a high-quality search engine, a social bookmarking system has several advantages over traditional automated resource location and classification software, such as search engine spiders. 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. Also, people tend to find and bookmark web pages that have not yet been noticed or indexed by web spiders. Additionally, a social bookmarking system can rank a resource based on how many times it has been bookmarked by users, which may be a more useful metric for end users than systems that rank resources based on the number of external links pointing to it.
For users, social bookmarking can be useful as a way to access a consolidated set of bookmarks from various computers, organize large numbers of bookmarks, and share bookmarks with contacts. Libraries have found social bookmarking to be useful as an easy way to provide lists of informative links to patrons.
Disadvantages
From the point of view of search data, there are drawbacks to such tag-based systems: no standard set of keywords (a lack of a 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, unorthodox and personalized tag schemata from some users, and no mechanism for users to indicate hierarchical relationships between tags (e.g., a site might be labeled as both cheese and cheddar, with no mechanism that might indicate that cheddar is a refinement or sub-class of cheese).
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. The more often a web page is submitted and tagged, the better chance it has of being found. 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, obliging developers to constantly adjust their security system to overcome abuses. Some social bookmarking websites added CAPTCHA protection to fight spam, but this can prevent blind users from registering for those services if accessible CAPTCHAs are not provided.

The Amazing Power of Words

When I was growing up there was a saying that sticks and stones can break my bones but words can never hurt me. That adage supposedly was teaching that it didn't matter what someone said to you. Insults were only thin air. Yet day in and day out I counsel people who were damaged by what someone else said. Only it wasn't the words that were the cause but the interpretation of those words. I wonder what percentage of us really means our words to wound our loved ones or friends. When my daughter was seven, my marriage was in shambles. I had been miserable for years, but despite my misery I didn't consider divorce because of my two young children. Then one day I got a letter from my mother asking me if I needed money for a lawyer, and soon after my best friend also suggested a lawyer, and my sister-in-law told me that if I had to make a quick get-away I could count on her to take us in. I couldn't figure out why they were talking of divorce since it wasn't on my mind! O...

What is Team Effectiveness?

Team effectiveness refers to the system of getting people in a company or institution to work together effectively. The idea behind team effectiveness is that a group of people working together can achieve much more than if the individuals of the team were working on their own. Team effectiveness is determined by a number of factors, such as: * The right mix of skills. Team effectiveness depends in part on bringing together people who have different skills that somehow complement each other. This can mean different technical abilities or communication skills. In fact, teaming up people who share the exact same characteristics is often a recipe for disaster. Team effectiveness depends on people taking on different roles in a group setting. If there is no agreement on who does what in the group, it is unlikely that the team will prosper. * The right motivation. Team effectiveness is directly linked to the interest that the group has on the project. If the job is too easy or ...
