As I don't have access to the logs of these sites, the second best approach is to look at the Alexa ranking of the sites. While it is far from being perfect, it seems to have a strong correllation to what Google Analytics reports for some other sites.
A few of the sites also have the ranking from previous years, but most of the sites were added only now.
Next year, when we'll be able to see how specific sites have moved will be much more interesting.
So if you'd like to add a site, send me the URL.
(nodeschool.is was added on 28 January when it was 51,701, but based on the graph I estimated that it was around 60K on January 1st)
