We also linked to the original source of those stats earlier in several threads. The telling thing to me is that article directories have taken a loss, and from other reports, a number of forums have too.
In recent years, both forum post links and article marketing became "easy" ways for some to promote their websites. From early analysis, it looks like those ranking demotions have also affected outbound link power from article directories and forum posts - so people who depended too heavily on those approaches may be suffering second-generation damage.
