So far, here is what I have figured out about the map:

    I believe that the only way to fix things on there would be for me to go to Bravenet and create a new map with the posts of where people are located spread out more.  I can do that, if that's what people want me to do, but I don't know how everyone would feel about it.  So, just wanted to throw that out to everyone.

     Also, as to a sort-of solution - If you click the zoom button twice, then the posts are spread out enough that you can access (I believe) all of them.
