You make some salient points. It's nice to have a place on-line to call home. Blogging, for me, is satisfying in that I have no editor directing what I write about. I take it seriously, however, weighing what I want to say with what I think will be useful to people, or amusing, etc. The idea of the 4Cs is interesting as long as a 5th C doesn't rear its head: conform. If blogs become like newspaper editorials, or are used to push agendas or products without transparency, then they will have outlived their usefulness.
