My Blog About My Blog

This year as a assignment I had to create a blog and update it weekly.  While it has been very easy points I am NOT going to continue to blog.  I feel that a blog is good if it is about one specific topic.  Like an informational blog.  Say I wanted to look up some facts about a certian topic,  I wouldnt mind reading a blog about said topic.  But I wouldnt want to read a blog about one peice on that topic and fourty other topics as well and have to sift throught the information to try to find what I was looking for.  I do not like blogs at all.
