I hate running across blogs that begin with "This is just me writing stream of conscience, cuz I don't know what else to write...." Stream of conscience is great in a written journal, where you barely have to lift the pen from the paper, or even in Word, Notepad, Works, Adobe... but not here where the rest of us can stumble into (the empirical 2nd person) your little piece of cyber space and read what it is you have to say.
Even on paper I am in the habit of censoring myself (those college professors that wanted "stream of conscience" papers turned in as homework assignments hated me), and I believe if you're going to share your musings with the rest of the world, you should take enough pride in them to exhibit your best.
Let's take a look at an example of stream of conscience writing: polar bears in cool climates how nice jelly roll eww too messy can't type fast enough vh1 is honoring queen this week cool Freddie too bad yer gone wish i was hang gliding whish of the wind in my face how fun bowl of cereal sounds good burn baby burn speedo
And what, in the greater scheme of anything, did that possibly teach us? Well, that the author of that sentence can't type as fast as the thoughts come, that the author doesn't think sequentially much, and that perhaps the author should consider writing on a full stomach.
Other than that? It's a waste of time. No plot, no character development outside of the static pronoun, no conflict, no resolution, no imagery, not even any punctuation!! (another pet peeve of mine).
On the other hand, it's a great way for writer's to jot down ideas in a trance-like freedom from formed thought, to read back later and use as a tool for plot creation.
Let me reiterate, it's a tool for developing plot, not a plot.
Okay, class dismissed.
