Coming back here after a day to look at why @surpassingoogle would have upvoted me on this comment was very interesting to say the least :-) My comment was absolutely not insightful but there was no other comment and you risk serious downvoting making posts like this so i chose for a positive approach and a pat on the back indeed. I have learned a lot reading all the comments on this post, don't want to waste my time checking out all these talked about posts, i actually think i would write something similar now, respect for the courage :-)
