Most the articles can be edited by anyone with access to the site. It has become the largest and most popular general reference work on the Internet. 

Wikipedia was launched on January 15, 2001, by Jimmy Wales and Larry Sanger. The name is a combination of a word from Hawai wiki that means quick and encyclopedia. Wikipedia idea was to join the  style of encyclopedia and the presence of a large body of popular knowledge. 

The open nature of Wikipedia gives huge problems; the amount of vandalism, the quality of writing and the accuracy of information. Some articles contain unverified or inconsistent information. 

Although having this inconvenient, Wikipedia is always the first place that everyone including me use, for its familiarity, simplicity and completeness.

Apple Open Directory

Apple Open Directory is the a directory service which stores and organizes information about a computer network's users and network resources and which allows network administrators to manage users access to the resources. 

Open Directory began with Mac OS X Server 10.2. In this initial form, Open Directory consisted of a network-visible NetInfo directory domain and a corresponding Authentication Manager service for storing passwords outside of the directory. Version 10.2 also included support for Kerberos. Mac OS X versions 10.1 and 10.0 stored user password information within the directory domain using crypt password authentication authorities, but version 10.2 paved the way for the current Shadow Hash and Password Server mechanisms. 

In a more general sense, Open Directory can describe the plugins model used by Directory Utility and the directory services framework in Mac OS X and Mac OS X Server. This could be thought of as analogous to the Name Service Switch systems of some other Unix-like operating systems.

Now this site is not working but it will be running this summer.

Originally funded by higher education, since Spring 2000, the JISC has been supported by both the further education and HE funding councils in the UK. In response to this change in remit, the RDN has been working closely with the FE community to develop its services to ensure their relevance to this new audience. 

RDN aims to significantly develop the content of RDN hub Internet Resource Catalogues (IRCs) for FE users. This will be achieved by increasing the number of resources in hub IRCs relevant to the FE community by collecting records enhanced with FE level and subject information from two major institutional resources. In addition, selected existing RDN resources will be mapped to FE level and subject information. These mapped resources will then be linked to the curriculum through the production of a number of subject-based showcase teaching packs.

As I said before about Wolfram Alpha, Bing can give instant answers; about sports like scores in a specific match, about a company for example its stock chart or the share price, convert units, mathematical calculations or find definitions direct of Encarta dictionary.

Finally Bing has incredible media features such as video thumbnail preview, image search w that has adjustable settings for size, layout, color, style and people, advanced filters or video search with adjustable setting for length, screen size, resolution and source.

WolframAlpha

Wolfram Alpha is an answer engine developed by Wolfram Research. It is an online service that answers factual queries directly by computing the answer from externally sourced data, rather than providing a list of documents or web pages that might contain the answer. 

Wolfram Alpha, which was released on May 15, 2009, is based on Wolfram's earlier flagship product Mathematical, a computational platform or toolkit that encompasses computer algebra, symbolic and numerical computation, visualization, and statistics capabilities 

Alpha differs from semantic search engines, which index a large number of answers and then try to match the question to one. 

Wolfram Alpha gives results based on computational facts. It is capable of responding to particularly phrased fact-based questions such as "Where was Benito Perez Galdos born?" or more complex questions such as "How old was President Barack Obama in 1974?" and generate a human-readable answer.
