Digg

"We started working on developing the site back in October 2004," Kevin Rose told ZDNet "We started toying around with the idea a couple of months prior to that, but it was early October when we actually started creating what would become the beta version of digg. The site launched to the world on December 5, 2004."

Kevin Rose's friend David Prager(The Screen Savers, This Week in Tech) originally wanted to call the site “Diggnation”, but Kevin wanted a simpler name. He chose the name “dig”, because users are able to "dig" stories, out of those submitted, up to the front page. The site was called “Digg” instead of “Dig” because the domain name “dig.com” was previously registered, by Walt Disney Internet Group. Diggnation” would eventually be used as the title of Kevin Rose and Alex Albrecht's weekly podcast discussing popular stories from Digg.
The original design was free of advertisements, and was designed by Dan Ries. As Digg became more popular, Google Adsense was added to the website. In July 2005, the site was updated to "Version 2.0". The new "version" featured a friends list, the ability to “Digg” a story without being redirected to a "success" page, and a new interface designed by web design company Silverorange. The site developers have stated that in future versions a more minimalist design will likely be employed. On Monday June 26, 2006 version 3 of Digg was released with specific categories for Technology, Science, World & Business, Videos, Entertainment and Gaming as well as a View All section where all categories are merged. Digg has grown large enough that submissions sometimes create a sudden increase of traffic to the "dugg" website. This is referred to by some Digg users as the "Digg effect" and by some others as the site being "dugg to death". However, in many cases stories are linked simultaneously on several popular bookmarking sites. In such cases, the impact of the “digg effect" is difficult to isolate and assess. Wordpress is especially hated among diggers for its tendency to crash under the increased traffic.

Viral Markrting

Viral marketing and viral advertising refer to marketing techniques that use preexisting social networks to produce increases in brand awareness or to achieve other marketing objectives (such as product sales) through self-replicating viral processes, analogous to the spread of pathological and computer viruses. It can be word-of-mouth delivered or enhanced by the network effects of the Internet. Viral marketing is a marketing phenomenon that facilitates and encourages people to pass along a marketing message voluntarily. Viral promotions may take the form of video clips, interactive Flash games, advergames, ebooks, brandable software, images, or even text messages.

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.

Widget

Embeddable chunks of code have existed since the start of the World Wide Web. Web developers have long sought and used third party code chunks in their pages. It could be said that the original web widgets were the link counters and advertising banners that grew up alongside the early web. Later, ad and affiliate networks used code widgets for distribution purposes. A widget is anything that can be embedded within a page of HTML, i.e. a web page. A widget adds some content to that page that is not static. Generally widgets are third party originated, though they can be home made. Widgets are also known as modules, snippets, and plug-ins.
Rich media, interactive entertainment widgets were first syndicated in large volume in 2001 by miniclip. Widgets are now commonplace and are used by bloggers, social network users, auction sites and owners of personal web sites. They exist on home page sites such as iGoogle, Netvibes, Pageflakes, SpringWidgets and yourminis. Widgets are used as a distribution method by ad networks such as Google’s AdSense, by media sites such as Flickr, by video sites such as YouTube and by hundreds of other organizations.

Social media optimization (SMO)

Social media optimization (SMO) is a set of methods for generating publicity through social media, online communities and community websites. Methods of SMO include adding RSS feeds, adding a "Digg This" button, blogging and incorporating third party community functionalities like Flickr photo slides and galleries or YouTube videos. Social media optimization is a form of search engine marketing.
Social media optimization is in many ways connected as a technique to viral marketing where word of mouth is created not through friends or family but through the use of networking in social bookmarking, video and photo sharing websites. In a similar way the engagement with blogs achieves the same by sharing content through the use of RSS in the blogsphere and special blog search engines such as Technorati.

Word of Mouth Marketing (WOMM)

Word-of-mouth marketing, also known as buzz marketing and viral advertising, can be highly valued by product marketers. Because of the personal nature of the communications between individuals, it is believed that product information communicated in this way has an added layer of credibility. Research points to individuals being more inclined to believe WOMM than more formal forms of promotion methods; the receiver of word-of-mouth referrals tends to believe that the communicator is speaking honestly and is unlikely to have an ulterior motive (i.e. they are not receiving an incentive for their referrals).

Trackback

A Trackback is one of three types of Linkbacks, methods for Web authors to request notification when somebody links to one of their documents. This enables authors to keep track of who is linking, and so referring, to their articles. Some weblog software programs, such as Wordpress, Movable Type, Typo and Community Server, support automatic pingbacks where all the links in a published article can be pinged when the article is published. The term is used colloquially for any kind of Linkback.

Social media

Social media is an umbrella term that defines the various activities that integrate technology, social interaction, and the construction of words and pictures. This interaction, and the manner in which information is presented, depends on the varied perspectives and "building" of shared meaning, as people share their stories, and understandings.

Tag

A tag is a (relevant) keyword or term associated with or assigned to a piece of information (a picture, a geographic map, a blog entry, a video clip etc.), thus describing the item and enabling keyword-based classification and search of information.
Tags are usually chosen informally and personally by item author/creator or by its consumer/viewers/community. Tags are typically used for resources such as computer files, web pages, digital images, and internet bookmarks (both in social bookmarking services, and in the current generation of web browsers - see Flock). For this reason, "tagging" has become associated with the Web 2.0 buzz.
