Just like the title says. Scraped 50k articles from various blogs around the net in a specific niche. Now what do I do with these? I'm guessing to aggregate them in a superblog and toss adsense on the blog for earnings. Should I credit the sources? Be wary of duplicate content in the big G? They were scraped from rss feeds primarily using a footprint of "Powered by Wordpress 3.0.1" + "keyword" + "/year/"
