Just found this on youtube.

A simple way to scrape web content from a site using Google Docs and Xpath.

I'm sorry but I don't get the point, what could this be used for? The only thing I see possible is to aggregate several sites in one spreadsheet and have it update each time we open it.. Right? What can we profit in terms of seo out of this? Spin and post the articles?

I use this to create my own databases.

For example when I'm building a city guide site I need some page to show hotel, hostels and b&b.

I use this method to scrape other structure details and descriptions...It's duplicate content, but it's always useful on a city guide and you will not be penalized.

This works for me...
