My cousin-in-law has, at least once.
I've done it several times, most recently the Tacoma Rainiers page on November 30.
(The "wow, they updated it really fast!" nature of Wikipedia is self-reinforcing:
1. I wonder if page X will already reflect news Y?
2. What, it doesn't?!
3. Well, I'll just add that part myself.)
I've made the same edit about three times - fixing the North American release date in the Final Fantasy VI article. Other people changed it back to an incorrect date (two different incorrect dates, actually) until I added a reference. I don't think I've edited any other articles.
