Q: Context: Web 2.0 describes World Wide Web websites that emphasize user-generated content, usability (ease of use, even by non-experts), and interoperability (this means that a website can work well with other products, systems and devices) for end users. The term was popularized by Tim O'Reilly and Dale Dougherty at the O'Reilly Media Web 2.0 Conference in late 2004, though it was coined by Darcy DiNucci in 1999. Web 2.0 does not refer to an update to any technical specification, but to changes in the way Web pages are designed and used., A website is a collection of related web pages, including multimedia content, typically identified with a common domain name, and published on at least one web server. A website may be accessible via a public Internet Protocol (IP) network, such as the Internet, or a private local area network (LAN), by referencing a uniform resource locator (URL) that identifies the site., Hacker News is a social news website focusing on computer science and entrepreneurship . It is run by Paul Graham 's investment fund and startup incubator , Y Combinator . In general , content that can be submitted is defined as `` anything that gratifies one 's intellectual curiosity '' ., A social news website features user-posted stories that are ranked based on popularity, as voted on by other users of the site or by website administrators. Users can typically comment online on these posts, and these comments may also be ranked in popularity. Since their emergence with the birth of Web 2.0, these sites have been used to link many types of information, including news, humor, support, and discussion. All social news websites allow the users to submit content. Each site differs in how the content is moderated. On the Slashdot and Fark websites, the administrators of the site decide which articles are selected for the front page. On Reddit and Digg, the articles that get the most votes from the community of users will make it to the front page. Many social news websites also feature an online comment system, where users discuss the issues raised in an article. Some of these sites have also applied their voting system to the comments, so that the most popular comments are displayed first. Some social news websites also have a social networking function, in that users can set up a user profile and follow other users' online activity on the website. , Fark is a community website created by Drew Curtis that allows members to comment on a daily batch of news articles and other items from various websites. The site receives many story submissions per day and approximately 100 of them are publicly displayed on the site, spread out over the main page and tabs (Entertainment, Sports, Geek, Politics and Business)., Reddit (stylized as reddit) is a social news aggregation, web content rating, and discussion website. Reddit's registered community members can submit content, such as text posts or direct links. Registered users can then vote submissions up or down to organize the posts and determine their position on the site's pages. The submissions with the most positive votes appear on the front page or the top of a category. Content entries are organized by areas of interest called "subreddits". The subreddit topics include news, science, gaming, movies, music, books, fitness, food, and image-sharing, among many others. The site's terms of use prohibit behaviors such as harassment, and moderating and limiting harassment has taken substantial resources., Slashdot (sometimes abbreviated as /.) is a social news website that originally billed itself as "News for Nerds. Stuff that Matters". It features news stories on science and technology that are submitted and evaluated by site users. Each story has a comments section attached to it where users can add online comments. The website was founded in 1997 by Hope College students Rob Malda, also known as "CmdrTaco", and classmate Jeff Bates, also known as "Hemos". In 2012, it was acquired by DHI Group, Inc. (i.e., Dice Holdings International, which created the Dice.com website for tech job seekers). In January, 2016, BizX acquired Slashdot Media, including both slashdot.org and SourceForge., Digg is a news aggregator with a curated front page, aiming to select stories specifically for the Internet audience such as science, trending political issues, and viral Internet issues. It was launched in its current form on July 31, 2012, with support for sharing content to other social platforms such as Twitter and Facebook., Subject: hacker news, Relation: instance_of, Options: (A) activity (B) collection (C) comment (D) community (E) day (F) feature (G) food (H) front (I) function (J) internet (K) multimedia (L) music (M) news (N) news aggregator (O) page (P) protocol (Q) science (R) server (S) set (T) sharing (U) social news (V) system (W) technology (X) text (Y) uniform resource locator (Z) user ([) voting system (\) website (]) will (^) work
