Wikipedia Immersion

While waiting for a few chess games to be over, I hit "random page" on Wikipedia many times and read many articles.  As I read some of those articles, I saw more than a few errors that I could have easily corrected and some stubs to which I could add information without much effort.  I soon realized that one could spend an entire lifetime reading Wikipedia and editing articles that are of interest.  Of course, I do not have that much time on my hands, but it would be fun just to spend an evening or two cleaning up some corner of the internet's encyclopedia.
