End of Posting?

I'm not sure if I will continue posting to my blog after this course. I personally do not know many people who would consider following my blog or would be interested in reading it. However, I do see where a blog would come in useful. Such as staying in tough with family/friends, keeping clients/customers informed...I have a friend who owns an art gallery that uses a blog to keep her clients informed on her activities and classes that are going on. It really seems to work for her.
