While Pageviews don't exactly have any significant value regarding your art, they do give you an idea how much traffic is peeking into your window. Occasionally, I notice an odd spike here or there for no apparent reason. Let's see... didn't post a deviation... didn't get any feature (that I know of)... didn't piss off a bunch of people (that I know of), and yet twice as many people as usual came by my little corner of dA that day!
Oh well. For whatever the reason, I hope they found something that made them smile!
