Hi Brad,
This is a good point. I think the pipeline question is a little too big
to slip into the middle of an existing question. I added a new question
that focuses just on the pros and cons of the pipeline. I also moved
the ITK specific questions at the end of the first page (How
understandable/easy/useful are the pipeline/streaming systems) to the
last page so that all of the ITK specific questions are there.
