There are many different types of blogs that discuss a variety of issues. As such, there are a variety of ways to the classify blogs. Simons (2008) suggests that there are 9 ways to classify blogs. Here are some examples of ways to classify blogs:

1. By Subject Matter

• Fashion

• History

• Environment

• Food

2. By Devices and Media Types:

• Photoblogs - Its focus is photography, and there are typically few words beyond a caption and comments (Gibson 2009).

Example: Shutter Maki

• Vlogs - Exclusively videos with text used only for captions, or text entries may be included (PCMag 2009).

• Sketchlogs - Blogs which potray the author's artwork or drawings.
  

Example: Kristen's Sketch Blog

I feel that the best method to classify blogs is according to its subject matter. By using this approach, people will be to find specific information pertaining to the genre that they are looking for. Wikipedia, for example, employs this approach.

Blogs are web-based platforms for authors to express their thoughts and opinions on any subject matter that is of interest to them. Although blogs have existed since the mid-90s, it is only recently that the blogging phenomenon has exploded to the size it is today (Blood 2000). So much so that it is getting increasingly difficult to pinpoint the exact number and types of blogs that now exist. However, sites like Technorati make an attempt to do so.

The blogging trend is sweeping through the continents at a pace never seen before. According to the Blog Herald, in 2005, there were a total of 62.66 million blogs in existence. Of these:

US/ Canada/ UK/ Australia/ NZ - 36.2 million
Asia - 24.35 million
Europe – 2 million

There are many reasons for blogging. In Europe, most blogs are based on topics such as the environment, music and wildlife rather than personal blogs (Best European Blogs 2007). On the other hand, in Asian countries, political, social and personal blogs are the current trend for blogging. In Malaysia particularly, political blogs make up almost 20% of all local blogs (Collette 2006).

Benefits of Blogging in Malaysia
Businesses and private companies use blogs to promote their products and services to a larger online audience. This in turn allows people easy accessibility to information that might be of use to them. One such example is Business Mentors.

During elections, members of political parties use blogs in hopes of reaching mass audiences. Lim Kit Siang's blog is one such example:

Blogs have now grown to cover almost all aspects of our lives and these are just some of the blogs available.
