Well right now my page is active for 3.5 months and got ~50000 hits so far. Should be enough for a decent statistics. I think most tools do not handle the redirect from www.blinkenlight.net to blog.blinkenlight.net properly.
In the end it is a marketing analytics tool like Google, Facebook and other "free" services.
Alexa is monitoring people who are trying to monitor other people??? Funny.
