A blog is a discussion or informational website published in the World wide web consisting of discrete, often informal diary-style text entries Posts are typically displayed in reverse chronological order, so that the most recent post appears first, at the top of the web page.Until 2009, blogs were usually the work of a single individual, occasionally of a small group, and often covered a single subject or topic. Previously, a knowledge of such technologies as HTML and File Transfer Protocol had been required to publish content on the Web, and early Web users therefore tended to be hackers and computer enthusiasts. In the 2010s, the majority are interactive Web 2.0 websites, allowing visitors to leave online comments, and it is this interactivity that distinguishes them from other static websites. However, there are high-readership blogs which do not allow comments. Many blogs provide commentary on a particular subject or topic, ranging from philosophy, religion, and arts to science, politics, and sports. The ability of readers to leave publicly viewable comments, and interact with other commenters, is an important contribution to the popularity of many blogs. However, blog owners or authors often moderate and filter online comments to remove hate speech or other offensive content. Most blogs are primarily textual, although some focus on art (art blogs), photographs (photoblogs), videos (video blogs or vlogs"), music (MP3 blogs), and audio (podcasts). In education, blogs can be used as instructional resources; these are referred to as edublogs. Microblogging is another type of blogging, featuring very short posts. 'Blog' and 'blogging' are now loosely used for content creation and sharing on social media, especially when the content is long-form and one creates and shares content on regular basis. So, one could be maintaining a blog on Facebook or blogging on Instagram.
