OMG! I just heard the news about Wikipedia adding NOFOLLOW to external links. For more than a year now, Wikipedia has been internalizing its linking in a campaign against spam. This turned into a witch hunt and the editors started removing all external links, even very useful ones. Further, it was severely affecting the usefulness of their wiki and led me to saying Wikipedia sucks. This did not stop the link spam. Did anybody actually think that would work? Now they've implemented a new strategy of using the NOFOLLOW attribute on external links. This is clearly a better approach, but adding this to its previous actions and they are looking like Google juice hogs. This will further increase the SERP rankings of Wikipedia pages. Yikes!
