it's like a lot of these 'caffeinated content' style products. Scaping Yahoo answers, articles etc and republishing it on your blog *won't do squat*. Think about it. Why should google favor YOUR version of some article you just scraped from articlebase??? It's already on articlebase! (which has a higher PR than your blog). Why would google favor your stolen text over Yahoo answers' own copy (given that yahoo has >ahem< a slightly higher PR than your cheap blog)? This sort of stuff worked in 2003. Nowadays you need to get cleverer. You need UNIQUE. It aint rocket science.
