How does having content scraped via RSS on to a site affect its value in SERPs? Is it safe to say that some scrape content on a given topic hoping that it will raise their page rank? For example, if you had a site that was very thin on original content, and the bulk of content on there came from RSS feeds scraped and redisplayed, would Google or another search engine see the scraped content and say, "Gee, here's a site displaying a lot of information on topic X, that passes muster", or does it not add in to their algorithms, or can Google's crawlers even "see" the material inside scraped feeds at all? And does it matter if the feeds were displayed by java, php, or in a frame? <phew!> lot of questions in there, sorry...
