The end of Weinberger!

So, what was the point of Weinberger?  He asks at the beginning and the end of the book if everything is miscellaneous, why doesn't it stay that way?  He then spends the entire book arguing in some ways that things should stay miscellaneous, and others that they shouldn't which left me confused.  Towards the end, he said that we work towards understanding and that in a conversation, we are looking for understanding and not just knowledge.  Maybe his point was that as he said, the third order leads to meaning, and that metadata and Web 2.0 are the understanding whereas the old style of books and encyclopedias are simply knowledge, not what people are looking for at all.  He also says that metadata scares people because order is lost and I think that is true to a certain extent, but will only be temporary.  I think younger generations growing up with metadata won't be scared of it, like DTC majors now.  We're not scared of wikipedia, or urban dictionary, or sites like digg.  In fact, some of us choose those websites over more reputable ones because we like the way information is stored on them better.  Metadata has become an important part of our lives, whether we like it or not.
