Speaking as a writer, the first question you need to ask yourself when going into detail is "Does anybody care?"

Most readers are not interested in page after page of exact detailed description. They just want the highlights and a good story. Sure, there's the occasional geek who'll read EVERYTHING, but most people when confronted with a session report the size of the Encyclopaedia Britannica will just skim it.

I used to write a campaign diary for our old 3.5 Legacies campaign, and even with cutting out all the irrelevant stuff, it ended up running to quite a length. I found that keeping it in-character, and reporting everything from the character's point of view, helped a lot. It's more personal and less dry that way. If you're interested, you can read the campaign diary here.
