I am not talking about content scrapping sofwares who steal content from your site/blog without your permission. I am talking about mashup site which uses content from good, big sites with huge content using their API and organizes the content on its site in such a way that user gets all the needed relevant info in one page.
1.How does google treat these site? Are they treated using duplicate content?
2.Are they treated like affiliate site which do not have anything to offer of their own?
3. What is going to be google's attitude towards this kind of sites when they sort out their caffeine?
