The term “Web 2.0” refers to a general trend of interactivity between users and a website. Examples include social networking sites, video-sharing sites, wikis, and blogs.
Web 2.0 sites typically include an acronym coined by professor Andrew McAfee, SLATES: searching (the ability to find information via keywords), links (commands that join disparate pages together), authoring (the ability to create content), tags (short descriptions of content that categorize and facilitate searches), extensions (applications), and signals (syndication technology that notifies users of content changes).
