I've not written in a PW group so don't know the difference there. I go back over what I've written sometimes after the initial read back, and get the similar themes and see what I can make out of it/them. For a poem that is.
I've written in poetry groups and the response is varied depending upon the group and teh subject matter.
I like the pace of the PW. Sometimes, lately, I've noticed I've not even wanted the music. The candle, the ritual, the peace yes. Though if I'm restless the music is a great help.
