What are people doing here?

My 'People Visited From' block (courtesy VisitorLocation) has been up for a little while now showing where the last 6 or 7 people have surfed in from since the last rebuild. Some of them are from pretty far away places: Australia, Iran, Peru, The Netherlands. Most are from the US. So it makes me wonder...how do people make their way here? How did they find this little blog of mine and what are they looking for that brings them here? I see a lot of Google and Yahoo! referrals in the logs. What do they think of what they find here? Not many of them leave comments, so they're all just silent visitors.
