User Contributed Map Update
The Virtual Tourism Readers map suddenly has hundreds of more entries.
Sadly most of the entries have come from readers of the Official Google Maps API Blog since they posted my tutorial a couple of days ago.
What has surprised me is how well the map is standing up to well over 300 placemarks. It used to be that Google Maps couldn't handle more than 100 placemarks very well. This map seems to be coping very well so far.
