I tried it out and it worked fine so far, except that I couldn´t link the marked spots on the map with an article link. i.e. if I mark Hamburg i want on a click to go to the accociated article "hamburg".
as far as I can see it works in a way that it displays the information that your enter as location info when creating the location. Once clicking on that spot the entire info is displayed. You have the WYSIWYG editor to enter your info, which in effect could be like an article with images and so on. You always can enter a link there that takes you to a seperate article page.
Otherwise I agree. For me as well it would be better if I could link the hot spots on the map directly to another page.
