At the rise of Search the public couldn't believe that a single search box could ever return adequate results from all over the web at all. SEO evaluated enormous, but when it comes to results that reflect your needs more exact SEO is not the holy grail. For example business apps do use other indexing mechanisme like metadata combined with a social distance in addition to ranking. I do believe the public gut feeling that SEO will not provide you with the right answer will become real in the end. At least a part of that feeling. I also believe that the quality of results could improve by adding the social component in SEO. So is it time to redefine gravity and implement a new model to assure that we still will find relevant and authentic information in the future? I do think it is time to innovate. Great article. Thanks.
