A blog is a type of web site that usually has some defining characteristics which separate it out from other web sites. These make it very like a magazine. They are:

• blogs usually publish in reverse chronological order. In other words, anything new appears on the home page and at the top of the home page. This is not always the case in other types of web site.
• Most blogs allow their readers to comment on what has been written by leaing comments.
• Blogs tend to be updated frequently.
• The majority of blogs are written by one person and strongly reflect that person's view and opinions.
• Blogs are very easy and often free to set up which has lead to a plethora of different blogs on a vast array of subject and in different writing styles.

The content of a blog post isn't always a text article. Some people post pictures they have taken or found. Others publish videos they have created or found on services such as YouTube or Blip.tv, while others simply publish links to articles elsewhere on the web that they have found interesting.
