Word cloud or tag cloud (or weighted list in visual design) is a visual depiction of user-generated tags, or simply the word content of a site, used typically to describe the content of web sites. Tags are usually single words and are typically listed alphabetically, and the importance of a tag is shown with font size or color. Thus both finding a tag by alphabet and by popularity is possible. The tags are usually hyperlinks that lead to a collection of items that are associated with a tag.

Bing (formerly Live Search, Windows Live Search, and MSN Search) is the current web search engine from Microsoft. Bing was unveiled by Microsoft CEO Steve Ballmer on May 28, 2009 at the All Things Digital conference in San Diego. It went fully online on June 3, 2009, with a preview version released on June 1, 2009. Notable changes include the listing of search suggestions as queries are entered and a list of related searches based on semantic technology from Powerset that Microsoft purchased in 2008.
