A blog (a blend of the term web log) is a
type of website or part of a website supposed to be updated with new content
from time to time. Blogs are usually maintained by an individual with regular
entries of commentary, descriptions of events, or other material such as
graphics or video. Entries are commonly displayed in reverse-chronological
order. Blog can also be used as a verb, meaning to maintain or add content to a
blog.
Although not a must, but most good quality
blogs are interactive, allowing visitors to leave comments and even message
each other via widgets on the blogs and it is this interactivity that
distinguishes them from other static websites.
Many blogs provide commentary on a
particular subject; others function as more personal online diaries; yet still
others function more as online brand advertising of a particular individual or
company. A typical blog combines text, images, and links to other blogs, Web pages,
and other media related to its topic.
The ability of readers to leave comments in
an interactive format is an important part of many blogs. Most blogs are
primarily textual, although some focus on art (art blog), photographs (photo
blog), videos (video blogging or vlogging), music (MP3 blog), and audio
(podcasting). Micro blogging is another type of blogging, featuring very short
posts.
As of 16 February 2011, there were over 156
million public blogs in existence.
