Blog day No. 3

Well, there is lots to this blog world that I don't understand. I sent out the canned invitation to my family members to read and respond to my blog, but the blog address wasn't clickable, plus it had about 25 letters and numbers suffixed to it. Who would want to enter that maze of characters?

Meanwhile I'm reading lots of blogs by others in the google blogspot.com system. You people are really good at making beautiful graphics, photos, and information. How does a reader respond to the blog? Do they have to be a "friend" with a google account? Can anyone respond in the "comment" section?

Oh boy, do I have a lot to learn!
