Since you're explaining so helpfully, can I ask something I've been really wondering about? On each bar of the bar graph, there are logged in LJ users and all visitors (I ignore 'page views' for the reasons you cite). Today there were like 20 non-LJ users who read my entry and I'm like O_o!! Maybe it's just because I'm always logged in, but who isn't on LJ and yet reading entries? Because you can't see your flist if you're not logged in, right? There's probably an obvious answer to this, but it's escaping me.
