As expected the U.S. is the first country where we see a massive adoption of Wikipedia. More surprising is the fact that the first states which were almost fully covered are Alabama and Arkansas.
The Netherlands are the first country outside of the US that lights up like a Christmas tree.
The strange white spot appearing early on in Central Asia are not because of a passionate interest in open content by the people of the Ferghana Valley, but rather people writing about interesting places in New York and leaving out the minus in the lat/long.
The Philipines light up way before most of the Non-Western countries.
In the last frame all the major population centers of the world are white. Except for China. No points for guessing why that is.
Wikipedia is a very important source for the content of Triposo - especially for sights. Wikipedia always offers the necessary background information. It's also an important source for ranking - the length of the article, the number of languages an article is available in and the the id of the article are all indicators as to how important the wikipedia community thought this article was.
The first two are quite obvious - the id maybe less so. Each entry in the xml dump of the wikipedia has an id. The lower this id, the earlier this record was created and to some extent the more important this article is. On average you'd think people would write about important things first before filling up the holes.
This reasoning lead to an interesting experiment: what if you would sort all geo-tagged articles by there id and then plot them in order on a world map? The movie above is the result of that experiment and shows how Wikipedia has spread over the planet since the start of the Wikipedia project.
