Definitely need that updated, it will also bring us more credibility when we tell our clients, no that is not the way anymore.
I also have a client who had previously developed this kind of linking strategy.
The poor guy probably spent hundreds of hours creating his links,on the old seo advice, and we have noticed a huge drop in their effectiveness. At the end of the day, his links were about keywords, not about content.
I think as an SEO, we have the responsibility to really make it clear to our clients that if they take a different approach, and create high quality community orientated content that contains some links, but is not all about the links they will not only benefit from the juice, but also benefit from google author rank.
I welcome the move towards quality content, as it means that genuine experts in various fields will now be heard.
