There are also other blogs which have a combination of styles which makes them hard to categorize. Otherwise known as hybrid blogs, can be identified by their purpose.
Such as the topics discussed in the blogs, the style of writing (formal or informal), format and audience.

Personally, the audience is the most crucial for all blogs as the main goal is to have people to read on the blog and contribute in turn. Thus the best interest of both parties would be achieved.
Therefore the right topics, style and format is crucial to attract the targeted audience.

Hence, with the targeted audience achieved, a community would begin to form around the blog which shares their same interest and contribute to it. Slowly as readers begin to leave comments, they begin to open up and contribute more. Which according to Cedar Pruitt (2005), the Pew study cites a rapid increase in the number of blog readers who leave comments, meaning that more and more people are becoming accustomed to participating in the social discourse that occurs in the "blogosphere."

An example of these blogging communities is http://www.usj.com.my/ , where communities in the area are able to get more information of their surroundings such as the new OCPD in Subang Jaya Police Station and other issues which interest the community.

How to create a blogging community?
Much rather it is the community which makes it a blogging community.
Although there are ways to help achieve this, which is by targeting the audience in the community. By understanding the needs of the community and being able to cater to those needs, the community would then realize the importance of the blog in their lives and begin to contribute towards it.
