I read writer's blogs mostly to know that the craziness I often feel about my writing is somehow 'normal' or at least 'understandable' by another writer, especially one that has created a career out of their writing.
William Gibson recently wrote about the mania of the revising process and thankfully the survival and resolution of said mania.
Mostly, he shows that yes, revising the "worst novel ever written" is not only possible but necessary, as is seeking the feedback from trusted pre-final readers. The 'editorial-ego' comes into play, but must be beaten back occasionally to prevent it from smothering (ever notice that mother is part of smother?...) the manuscript.
It all goes back to that idea that manuscripts are never really 'finished' (ie perfect) but abandoned (hopefully with the knowledge that it's polished enough for submission).
