The title is misleading. It should be "Lessons learned about web crawlers while crawling the web"

I think it should be called 'web scraping 101'

Very thin article.

I found certain aspects of it really interesting. In particular, the way that the author interacts with the crawling software to gain insight into the structure of a website. Not just the process, but the way he interacts with it is interesting too.
