A blog is basically an online diary or journal that digitally records about anything you would want people to read. “Blog” is short for the term weblog and a term coined in humor in the late 1990′s. They come in different styles and formats, support and settings, all depending upon user preferences. Most blogs are primarily textual, although some focus on art (art blog), photographs (photoblog), videos (video blogging), music (MP3 blog), and audio (podcasting).
Of the numerous topics displayed by blogs, perhaps the best known are political, personal, niche, travel, health, religious, and educational. All serve to be a collective of a specific topic written or produced by an individual or by a group of people.
