I would like to see the number of hosts a user has show up on the detailed stats page, very similar to the user's detailed stats page for individual projects, but the number could be the link to the host list (to match what was done with position). And the "comparison to users with same number of hosts" is a nice feature.

Number of hosts [ link to host list ]
Comparison...blah...blah... [ link to comparison ]

BTW: Great job with the site Willy!
