|A blog (aka weblog or web log) is a Web page that is frequently updated, usually with personal insights and links. Each blog entry is typically short and to the point, sometimes with a link to a longer, extended entry.
Traditionally, blogs are used as something like an online diary. They often include links that the author had found interesting that day as well as life stories.
As blogs became more and more popular, they started to be used for other things too.
For example: Journalists might post their stories to the blog and readers subscribe to the blog news feeds to receive up-to-the-minute information on a variety of topics.
