Bellow there were the 18 pages I used in a presentation on Social Media. Each page is like a slide in Power Point. Having paused to take comments I should add these too - make it Wiki-like. In my social media website in wordpress I can offer a password to each page. Why? To practice what I preach. Collaborate. Two minds are better than one and many are better still. I see this here to indicate that a blog is but a collection of affordances; you can do as you wish.
