I didn't think that far, but you are right, this becomes necessarry.
What worries me a bit in this though: If you pan over to Berlin and
Beijing comes out of sight, it will look as if suddenly the Berlin-polls
become more active. Maybe a little message "Re-calculating the views"
would help? But it doesn't seem ideal, does it? What else could we do?
When zooming in or out this problem wouldn't occur, because the whole
picture changes anyway.
@ Mike: Concerning Zoom and Pan: For me personally the most fun way is
to use the scroll-wheel to zoom in and out and to grab the map with the
left or right mouse-button to pan.
@ Marcos: I must admit, how to project the tags onto a map will probably
remain a mystery to me. But if you and Pietro know this ... ;-)
