How to publish the Places map from Aperture with geotagged pictures?
One solution that I used before is to publish it on Flickr and use their map feature. I think I can directly share the link to the map with my friends. One needs to make sure to include geolocation data when uploading. 

As an aside, not crazy about Flickr anymore, my subscription is about to expire and I would like to find something else, hence the question !

EDIT: A better solution seems to be picasa, with an upload to picasa web and options to get a google map online or a Google Earth kml file.
