Great to separate the world into regions (vs. countries) that are actually worth seeing. Countries are often too big to make sense to count as "having seen / been", e.g. Colorado is a lot different than NYC, or Moscow vs. the far east of Russia. It's also great for researching a location and goes way beyond the usual lists of UNESCO World Heritage Sites, suggesting interesting museums and other sights or even boat rides. It's also great to keep track of traveler friend and organize trips together
