Wikipedia needs no introduction. It was started in 2001, collaboratively developed by the community of volunteers, which now has 70000 active members world wide. With 30 million articles written in 287 languages it is one of the biggest website.
Not only the content is accessible to everyone. On http://dumps.wikimedia.org you can find links to database dumps, and page view statistics.
The questions is: Can we use those logs to tell something about people? Is it possible to identify trending topics? And if something is happening in the real world, is Wikipedia a source to read about that?
