I was a little worried looking @ my clustermap.  The small picture on the main page shows a lot of dots.  When clicking on it, your got the full view (Click here).  Most of the Dots are disappeared.  But after looking around, it seems that they have archived the Stats.  So on your main picture you still see the total amount of Dots.  On the Detail you see the dots from 19 June 2007.  And when clicking the archive, you see the dots till 19 June 2007 hehe.
