If you want to show where you have been, countries and cities you have visited you can create a “Where I have Been” type map on TripAdvisor Gadget. This is run via a Nicely coded AJAX Web App! I have uploaded mine below, hopefully you can see my TripAdvisor Gadget map below.
I am a very active user of TripAdvisor ad I have almost 600 reviews at this point. TripAdvisor is a great application and I have never been let down by the system, The reviews are normally very good and a great way to make a decision on a trip or a restaurant.
