blog (a contraction of the term weblog) is a type of website, 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.
Many blogs provide commentary or news on a particular subject; others
function as more personal online diaries. A typical blog combines text,
images, and links to other blogs, Web pages, and other media related to
its topic. The ability for 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 (artlog), photographs (photoblog),
sketches (sketchblog), videos (vlog), music (MP3 blog), and audio
(podcasting). Micro-blogging is another type of blogging, featuring
very short posts.
