It's a really good exercise to hit Random Pages 10 times.
I tried it and mostly got vanity pages for people who did something, but didn't seem too important.
One I got is about the mayor from 1995 to 2001 of a Texas town of 75,000 people. I suppose it has some value to the people who lived in that town or need to research about it... but I can sympathize with the problem of trying to decide what is useful and what is not.
Another one is an article on the Tigress character in Kung-Fu Panda. I mean, sure, it was information, but the extent of its vitality to human knowledge and literature?
Another one is a 7th round hockey player from Canada...
I mean, should Wikipedia really keep track of all athletes, all mayors, and all characters in all movies?
I think it's a better idea to keep track of more permanent stuff and let fans of these athletes, mayors and cartoon characters make websites about them.
