How to blog 101

I have signed up for a class on creative, scintillating, exhilerating blogging. I need some pointers and direction and here, to the rescue, the artbizcoach, Alyson Stanfield, http://artbizblog.com and creative nomad,Cynthia Morris, http://journeyjuju.com. Sound like the perfect teachers to me.
Who am I trying to direct my blog to? I would love for my friends and family to tune in and see what is going on in the creative part of my brain. Potential collectors, galleries and customers for illustration (possibly in publishing or art directors)are an audience I am trying to reach too. Living near or far isn't an issue to me with the technology available. A gallery on the other side of the world would be an interesting challenge for shipping, but doable. Creating a dialogue with or receiving comments from these readers would be interesting and help fill the silence when I post things.
So many people have little time to surf the net so I would like to offer a good short read and a visual to go with it for the readers in a hurry. I really enjoy writing so would like to add an asterisk and something creative for anybody with a cup of coffee or glass of wine and some "down" time. A daily painting could be part of this too. The first blogs I did were based on the journal pieces I was working on.
I think that is the answer to blogging 101, question 1, part 1 and part 2. Sure helps to think this through and put it down in writing.
