The first time you generate a map there may be a long delay if you have a lot of contacts!
This is because we have to retrieve the profile for each of the contacts the first time. After the first time, generating a map will take a lot less time. So after you click the link to show you your map, please be patient for a while before giving up and closing your web browser, or moving to a different page. We will be adding support for Canada in the near future. As soon as Yahoo! adds support for Europe and the rest of the world, we will follow suit.
