It's a common sentiment on Hackers News. It presupposes that the purpose of writing and reading is to extract the maximum amount of information in the shortest amount of time. Presumably, if we all lived in this manner we would also:

* Blend all our food so that we could extract the maximum nutrients with the minimum amount of chewing

* Only watch movie trailers to get the main plot points without wasting 90 minutes

* Request friends to get to the punch-line of a joke without all the boring wandering around of the story

There are many reasons to read, as there are many reasons to travel. Sometimes it's only about getting to the destination as quickly as possible, and sometimes the journey is part of the experience. The question is whether you as the reader and the writer are on the same journey together, or you're looking for business travel while they are on a slow train enjoying the countryside.
