Squidoo, a huge user generated content web site founded by Seth Godin, announced they are now nofollowing all outbound links.
I am surprised it took so long. It was founded in 2005 and has been used by SEOs for years for getting links or content into Google. I believe Squidoo was hit hard after Panda.
That being said, Squidoo said:
Based on the successful implementations of other authoritative sites, like Wikipedia, Squidoo will now apply “nofollow” markup to all outbound links. This means that any link shared on a lens will work exactly as it always has for you and for people visiting Squidoo, but search engines will no longer use it as a signal for ranking.
In 2010, Squidoo had 1.5 million hand-built "lenses" or pages.
Not a big surprise. Made me money, served it's purpose, one tool in an arsenal that now is less effective, oh well right?
