Really - you think all the great literary masters agree with you? Such confidence.
A few thoughts on word vomiting:
First, it doesn't preclude the nuance and precision needed to do great philosophy. I know this because, as is well known, Kripke word vomited the entirety of Naming and Necessity, which is full of analytic nuance and precision.
Second, I find that word vomiting can help me to trace a thought down avenues I previously hadn't taken it. That is, just "letting it flow" allows my thought to go in a bunch of different directions and see new possibilities for it. Of course, almost inevitably, the word vomited paragraph(s) will be entirely erased and replaced with a more carefully written argument. But nevertheless, the word vomit can help on the first try to see new ideas.
Third, it usually takes me about an hour and a half to write a well written double spaced page for topics I'm not terribly familiar with. For topics that I am familiar with, e.g. Heidegger or Kierkegaard or the epistemology of disagreement, I can write a good page in about half of that time.
