I agree that clustering is a good idea.
However, it might be usefull to e.g. say "a cluster can at maximum be 50
(or 30?) developers" or so - just to make sure we don't get too few
points on parts of the map with many developers (it works quite well if
one is not on the "view the world"-size). I think that even the first
map should give you a good graphical impression of the geographically
distribution of Debian. (It would become better if the clusters could be
of different size depending on the numbers.)

Well, I wouldn't like it for my data - but my data is inaccurate by way
more anyways :)), so I don't mind too much for the map.
