My first attempt at blogging.

As part of my teacher training I must learn how to blog. I am told this will help me move into the 21st century. I am a little opposed to this type of communication because there is no face with which I am communicating. It makes it all too impersonal for me. One is fearful of that which one does not understand and this is one of those things I don't understand. Why spend time talking to my computer? What is there in blogging that I should be interested in?
