I would spend time asking the kids for names for what they want our blog to be. Suggestions, and see how they wanted things to work. I would use a projector to show what is on my computer to show the kids first hand what they will be doing.
I know our three computer teachers. They are called our LSTC's. I have a great relationship with one of them in particular, and she and I get along very well. She has come in to my computer lab this year and gone above and beyond to make sure that things are connected and working like they should. This whole thing could eventually take off to ways that teachers, parents and students couldn't possibly imagine.
All of this can and will be incorporated into my teaching. I would eventually like for this to be done by the grade level.
