Here are my comments/feedback transcribed from the showcase:
"very informative. The 'crossing off' feature for visited sites is nice. This would be a great research tool"
"very interesting. I wondered a little bit about the purpose of it, but for what it is, or anyone who was interested in spiralism, this site is very helpful"
"I liked the way after you visited each link, it crossed out the link, so you don't look at it again."
