As well as talking about your use of blogger, you should also compare this to another service, eg tumblr.com or twitter.com. These are quite different as they are designed to be micro blogs which are by definition shorter and often used just to share links or comments about things. They also tend to have people adding short comments.
Add a section to your blog about micro blogs, setup and try out tumblr.com and show how tumblr blogs tend to be different to stand ones.
