Submission for the October 2011 Coding Challenge/Wikipedia Slideshow.

"Evolution is a change from an indefinite, incoherent, homogeneity to a definite, coherent, heterogeneity, through continuous
differentiations and integrations." ~ Herbert Spencer, First Principles (1862)

WikiJoy is a [new] way to transmit Wikipedia articles, it make possible say: "This article give me joy, and worth". In other words, its a user friendly form to avaliate content from a article.

So, when you read a article and enjoyed it, you can vote in the page content, approving it.

The project itself is a double side app:

* the user side just send some informations (page id, city and language) to the server;
* server receive data from users and save it in a database, and make this data avaliable by a simple API;

A possible problem would be create a empire of "pop" articles, but using more data from Wikimedia dumps is possible get ranks by Category, and spread [good] articles from any subjects. And using API its easy create new applications describing trends and good content.
