Ain't is so? Don't you just love it when someone comes along who has read all those posts over the past 5 years here at WebmasterWorld and so succiently and informatively just wraps it all up in a handbasket so that we don't have to weed through those hundreds of posts to get to the wisdom?
Our every understanding is significant. Our every mis-understanding is significant. Most often new ideas are the mutation of an idea previously held. Novel ideas do not come out of the mist of obscurity, but out of the mass of knowledge we already have before us.
Those 5 years of posts you are talking about are a mishmash of insights. This post by sugarrae is an amalgamation of the wisdom disparately accumulated here over the years, a cohesive epiphany, much to be lauded, and for none to be deplored.
