I wanted to be clear that I am not trying to be argumentative or know-it-all, just throwing around some ideas and my own theories (for what they are worth) after many weeks of thought on this topic. I tend to get wordy and type very quickly, so my wording can sound abrasive. I hope I didn't come across that way.
I appreciate your input/thoughts on this and hope others will have some input on this subject. I am very intrigued by the website credibility studies, and have been giving a lot of thought to how those human signals can be incorporated into the algorithms. Anyway, I felt compelled to say this so you didn't think I was dismissing your points.
