Which is why my blog is a "writing exercise," as you put it. I believe people can be more engaged with their media, but it is admittedly easier to go for the slogan-style messaging nobody has to think too hard about. I dream of a world where everyone has valuable, well-considered input and I will continue to write as though I live in that world until we get there.
Asking someone who wants to practice the art of writing to do otherwise is no different than asking a painter to just make stick figures.
