Blogging???

You know to be honest with you I have no idea what I am doing.  I talked with my friend Mary and told her I feel like I am writing a diary that the whole world could see if they were interested. She said yes that is what this can be.  Well since I have no followers, no commenters, no interaction of any time am I doing this right?  Am I just writing a diary for myself?  Not complaining but since I don't have someone holding my hand during this process and know no one that blogs what in the blazes am I doing?
