Read the second link.
Own words? Most of the blog posts are done by people much smarter than me. I could do a 1 or 2 hour PPT Presentation trying to get to the point. I think only a few people would be able to follow me. Not, because I am so tremendously smarter than them (I have a PhD), but because the topic is so tremendously complex and interlinked.
