I was just looking at the Yahoo home page and there is a short snippet article about detecting photoshopped images. It links to boingBoing, which links to the source.
Why is Yahoo linking to boingboing and not the actual source of the article? My guess is that someone inside Yahoo (who posts these things) is a boingboing fan and wants to do them a favor. It just feels wrong to me that a high ranking site would link to a blog talking about an article rather than the article itself.
