This is a great tool! In a past life we needed a web scraper to pull single game ticket prices from NBA, MLB, and NHL team pages (e.g. http://www.nba.com/warriors/tickets/single). We needed the data. But, when you factor in dynamic pricing and frequent page changes you are left with a real headache. I wish Kimono was around when we were working on that project.
I love how you can actually use their "web scraper for anyone" on the blog post. Very cool!
