What Am I Doing?

What am I doing?  An old dog learning new tricks. I'm almost 49 and am going to venture into the Blog World and see what happens.  I have no idea how to do anything and I don't know anyone who has a blog so this process should be interesting.  Am I too old to figure this out?  Will anyone see it?  I'm not telling anyone about it, let's just see what happens. . .
