It is an excellent read because it is well-written and gives a unique perspective that does not pretend to be proven facts. Most Internet news stories these days churn out facts in quick time, often with poor grammar and no creativity. When opinion creeps into those pieces it is more insidious. This blog is written in an older style that is more full-bodied in thought, taking tenuous connections and facts to try to point to something that cannot be proven. Compare it to opinion pieces in printed newspapers a couple decades ago, and it would be similar. You just need to keep perspective when you read pieces like this, and take them how they are meant.
