You're definately on to something...
From my - fairly new...only one year of... - bloggingexperience I can definately conclude that blogging, picturesharing, wikis etc have brought a lot of intuition into my writing and working-processes.
I've always been a very intuitive person in person - so to speak. But in my writings I've always been...let's say somewhat anal. Opening up the writingproces and inviting others to share their thoughts and reactions on ideas and scetches was very frightening to me in the beginning. But I have learned to really appreciate it and have definalety been given a lot back. Intuition rules.
