Do you think there might be another category of writing, that fits in an essay: story telling?

Some of the most compelling talks I've been to are stories winding through a narrative. Conciseness doesn't really fit it, and it is certainly designed for discovery more than persuasion. But it's a bit of both, characterized perhaps by discovery of the audience - though not necessarily of an intended idea, which would make it persuasion.
