Blogs are more permanent than posts to an online discussion list, more dynamic than older-style home pages. They are more personal than traditional journalism, and definitely more public than diaries. A blog is often a mixture of what is happening in a person's life and what is happening on the Web, a kind of hybrid diary site. So, there are as many unique types of blogs as there are people.

Blogs enable interaction and invite others to reward a persons creative effort with feedback. They weave new social networks, introducing people with common passions. Another reason why one should start blogging is dissemination of "micro-opinions" important to a small audience opinions that would never make it in newspapers.

Weblogs, definitely, are the mavericks of the online world. Two of its greatest strengths are their ability to filter and disseminate information to a widely dispersed audience, and their position outside the mainstream of mass media.
