I had never seen this before. I will check it out, at least for inspiration.

I'd say "scraping" is a little more focused on extracting data from specific pages as opposed to ALL pages as in "spidering", but the two are certainly cousins if not siblings. Anemone would probably be good at the same sorts of tasks Upton is designed for (i.e. scraping data contained on multiple pages).
