I have a couple of blogs. One is about my transition from life after teaching. It is kind of a diary style and really helped me to clarify things. Only a couple of close friends follow and comment on it.
My other blog is associated with my parenting coach business. I use it to list articles and interact with my target market. I often leave links to articles I've posted here and vice versa so it helps with my traffic a little bit.
There are two reasons I can think of that might entice you to "try it." Blogs are great places to write about non-evergreen content or things that wouldn't do as well on hubpages. The other reason is there is another entirely different type of community out there where you might find additional inspiration...but just a warning..no writing community is better than the one here at hubpages:)
