Excellent post and very insightful; just one thought, and that is where does curation fit into your figure? I wrestled with three possible answers:- 1, It goes across each of the areas you list from content management to self publishing but as a separate box. 2. It is part of collaboration tools 3. It is a verb, not a noun, explaining the generic actions carrying out each of the content management to self publishing boxes. Can I be so bold as to ask your view?
