This sounds like a really awesome idea for a Wiki:

When I backpacked across Europe, many of the places we visited were due to the suggestion of people we met in hostels. This seems like a good way to transport that experience onto the Web that's more adaptable and less compressed than the travel guides, though its still not a replacement (e.g. it needs some maps and the content is still being created).
