Semapedia: "What do you get when you combine Semacode and Wikipedia? Why, Semapedia of course. The project is the brainchild of Alexis Rondeau and Stan Wiechers, and basically what they encourage you to do is to place place tags on places and things to link them to the relevant Wikipedia articles. So, as you can see in the picture, you've got a link to Lower East Side that's in the Lower East Side. It would be amusing if they posted that picture into the Wikipedia article on Lower East Side ... heh. Anyway, I think that properly applied it's a pretty good idea. For example, it could be linked also into Wikitravel articles for tourists. Apparently there is substantial interest from around the globe -- check out the semapedia blog."
