I think there needs to be some sort of balance between the two. I tend to be a really concise writer, which is why I have a heck of time writing anything that's longer than a few pages. Everything I write tends to have a 'here's what happened, the end' pattern, and really, who wants to read that, especially if it's something for the purpose of entertainment (like fanfiction)? On the other hand, I also don't want to be buried in things like my Organic textbook, which babble on for pages at a time about things that a) I really don't need to know or b) could have been said in a couple of paragraphs.
