john cox made me aware of the most excellent alexa traffic analyzer. because alexa runs as spyware in the browser, they are able to collect lots of interesting data. and they make it available for analysis too, which i hadn’t expected.
interestingly, they fold subdomains into the top domain. i take 85% of all traffic going to *.abstrakt.ch. they currently only collect data from internet explorer users, so they may be misrepresenting sites with a large geek audience. also, they state that statistical significance is an issue for sites not in the top 100k.
