Changed by blogging

Seth Godin makes a nice point about blogging.

It does indeed force you to be clear. Clear in your writing for one, but also clear about yourself. Who you are and what your point of view is. I'm only just starting to become aware of that aspect of blogging and it's enlighting.

But it also makes you wonder about you added value in life. Can you provide insight to others or are you just a rambling fool? Anyone care to comment?
