Well, it's probably good to look at Uniques and Pages together. The closer they are together, I'd say the more "regulars" you have, or actual visits (visiting 1-2 pages and leaving indicates someone coming to see an update, specific page,.... or at the very least a click by a stranger, not liking what they see, and leaving

)
The more pages viewed you have, in relation to uniques, should indicate a visitor looking through your archives, or at least clicking around your site. Regulars will already have clicked on everything, unless you updated a page somewhere.
At least that's my interpretation. Like When I check my GoStats after a Big Project Wonderful ad Campaign, my uniques go up, but my hits go WAY up.
