A visual matrix of aligning elements of community with terms

Well, having thought a bit more about semantics and definitions, I thought I might try and create a visual matrix of trying to distinguish the terms. So I am not sure given the confusion of definitions whether this is useful or not. I do believe that the underlying elements of community is what is important, so maybe we can graph groups, networks and CoPs (to use three) along three dimensions. I would like to add a fourth, which is difficult to graph visually (maybe could do the lvel of brightness, share of colour or something to that effect.

I used MS Word drawing toolbar to do this.

What do people think, is this helpful? Use alternate dimensions, suggestions for a fourth?
