Wikitravel is a project to create a free, complete, up-to-date and reliable world-wide travel guide. So far we have 27,250 destination guides and other articles written and edited by Wikitravellers from around the globe.
Other sites that would likely be of interest to travelers. (Perhaps rock climbing wiki, sports wiki, map wiki, travel law, etc.,.)
Wiki tht probably shouldn't be linked as neighbors:
the Symbol Project wiki - very tangential, very fringe - if you're going to do something like this, it would probably be Wiki Travel linking to a Maps wiki linking to a Public Symbols wiki linking to the Symbol Project
consumerium - one day, people interested in learning about travel will want to visit consumerium, but that day isn't today - what would be better, would be a "global shopper wiki," for people who like to buy things around the globe, and then link both Wiki Travel and consumerium to THAT wiki
visual wiki - same reason as symbol project wiki
Wikipedia, Switch wiki, book reviews - these should be linked from the wiki nodes wiki; We can't be putting all these universally applicable wiki on every single wiki node in the world; there will be more and more useful utility wiki; no point in listing them all everywhere
We have two problems right now:
Foreign languge wiki: We don't know foreign languages, so we can't write wikinodes very well for them.
Non-existant wiki: While you'd like to link to say, a wiki about maps, from the travel wiki, or travel law, you can't realisticly do it, because those wiki don't exist yet.
