I have information like this on Flickr, and I found it fascinating. I check it every morning. What photos were looked yesterday? How many times? Were they direct traffic? Did someone post my photo on their site? Dead useful info!

So I signed up for this lijit thing. Wheee! Take a look below!These are my ligit stats.
Ooo, a pie chart! Doncha just love those? There's a graph showing the number of hits my sites (the ones I've included) get every day (oooo!), the pie chart breaking it down into sources (how many googled? how many direct?), a list of the locations in the world that accessed my sites, and a handy map showing the viral spread of the marfnet! See the little dot off the coast of China? Who could that be? (Hi, Marleeeeeene!)There is also a widget, the lijit "wijit," that will search a list of your included sites. No one has used that yet. I might at some point, when I've lost track of what I'm writing about where. This is embedded in my blogs.
Another really useful statistic is a list of popular search terms. What were they looking for when they found your site? Information like this will help me pander to the lowest common denominator - mwah-ha-haaaa! - and tailor future blogs to lure in the unsuspecting, people who really are looking for someone named Richard Hertz (Dr. Dick to the rest of us).
I really enjoy this tool! (Hee! I said "tool"!)
