"This weekend saw a number of prominent technology observers questioning the value of social networks, including This Week in Tech host Leo Laporte, who penned a thoughtful post on why he's leaving Google Buzz behind. Laporte said he feels that his last four years of social networking use have been an "an immense waste of time," but I think he and others are missing the larger point. Too many people seem to be trying to use social networks for media and marketing activities instead of the core reason such networks exist: namely, to connect people."

"Google is currently the most used search engine. It has one of the largest databases of Web pages, including many other types of web documents (blog posts, wiki pages, group discussion threads and document formats (e.g., PDFs, Word or Excel documents, PowerPoints). Despite the presence of all these formats, Google's popularity ranking often places worthwhile pages near the top of search results."

"The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail."

"The word "cyberspace" was coined by the science fiction author William Gibson, when he sought a name to describe his vision of a global computer network, linking all people, machines and sources of information in the world, and through which one could move or "navigate" as through a virtual space."

"cyberspace (1) A metaphor for describing the non-physical terrain created by computer systems. Online systems, for example, create a cyberspace within which people can communicate with one another (via e-mail), do research, or simply window shop. Like physical space, cyberspace contains objects (files, mail messages, graphics, etc.) and different modes of transportation and delivery. Unlike real space, though, exploring cyberspace does not require any physical movement other than pressing keys on a keyboard or moving a mouse. "

"Cyberspace is the electronic medium of computer networks, in which online communication takes place.[1] It is readily identified with the interconnected information technology required to achieve the wide range of system capabilities associated with the transport of communication and control products and services. Current technology integrates a number of capabilities (sensors, signals, connections, transmissions, processors, and controllers) sufficient to generate a virtual interactive experience accessible regardless of a geographic location."

"The World Wide Web (known as "WWW', "Web" or "W3") is the universe of network-accessible information, the embodiment of human knowledge. The World Wide Web began as a networked information project at CERN, where Tim Berners-Lee, now Director of the World Wide Web Consortium [W3C], developed a vision of the project. The Web has a body of software, and a set of protocols and conventions. Through the use hypertext and multimedia techniques, the web is easy for anyone to roam, browse, and contribute to. An early talk about the Web gives some more background on how the Web was originally conceived. "

"The World Wide Web ("WWW" or simply the "Web") is a global information medium which users can read and write via computers connected to the Internet. The term is often mistakenly used as a synonym for the Internet itself, but the Web is a service that operates over the Internet, as e-mail does. The history of the Internet dates back significantly further than that of the World Wide Web. The hypertext portion of the Web in particular has an intricate intellectual history; notable influences and precursors include Vannevar Bush's Memex,[1] IBM's Generalized Markup Language,[2] and Ted Nelson's Project Xanadu.[1]"

"he World Wide Web, abbreviated as WWW and commonly known as the Web, is a system of interlinked hypertext documents accessed via the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia and navigate between them by using hyperlinks. Using concepts from earlier hypertext systems, English engineer and computer scientist Sir Tim Berners-Lee, now the Director of the World Wide Web Consortium, wrote a proposal in March 1989 for what would eventually become the World Wide Web.[1] At CERN in Geneva, Switzerland, Berners-Lee and Belgian computer scientist Robert Cailliau proposed in 1990 to use "HyperText [...] to link and access information of various kinds as a web of nodes in which the user can browse at will",[2] and publicly introduced the project in December.[3]"

"The internet has changed the lives of people around the world. It has never before been easier to acquire various types of information and to reach people around the world by entering social online networks, such as Facebook. However, the infinity of the internet also leads to information overflow. Likewise, the majority of social online networks address private people, oftentimes leaving the opportunities from which the professional world could benefit unused. Thus, modern web tools which filter information and social networks that enable people to easily communicate, network and share knowledge with each other in the professional context are a tremendous help.
