The gmap location block looks nice, but it only shows the user location that he entered. He already knows where he is (we hope). What he wants to know is whether there are other users nearby. Showing the entire gmap/node of users is too much, it could encompass the whole world.

So we want to build a view of those closest to the user, so we need to use a proximity filter. There is even an option to base proximity on distance from the user, but here we have a problem. Our location is based on the profile node, not the user.!

How can we get the proximity field and filter to work?
Maybe I need to move the location to the user, but will the nice profile popup still work?
Maybe there is another way? Can we compute the proximity somehow using the user’s profile location?

It seems that there are several ways to configure location:
1. Based on the user
2. Based on the node with content profile
3. Based on a CCK field with content profile
The discussion here http://groups.drupal.org/node/23030#comment-83259 indicates that #3 is the way of the future. Even if it doesn't solve our problem with proximity yet. So I am going to uninstall location, then reinstall without turning on node or user location.
