Would anyone want to read the story of your life? On a gaming scale, would recounting your adventures of the day sound like an adventure? For we the bloggers, one way of measuring how interesting a play session was is whether there was anything worth blogging. If you did not do anything worth speaking of, why did you do it?
Contrast: Ravious is blogging daily about his adventures in Rift, while I mentally summarized my weekend play as “I did two quest hubs worth of Forochel on my new Warden.” New and exciting tends towards extremes of good and bad, with new insights to be had, while my third trip through Forochel yields nothing new. A strong argument against the twentieth day of running dailies plus an instance is that your only likely story is that someone you grouped with was brilliant/awful.
If your story is not growing, you are not growing.
