Our school bans wikipedia on their network, doesn't buy any online encyclopedias, rarely buys text books, and tells the kids to "research" stuff on their own - aka google search.
Then it could be a good thing if Google restricts search to your school, wouldn't it? Because then the school would be forced to acknowledge the mediocre job they're doing and do something else. If your school already does such a poor job, then perhaps you should hope that the tech they do use collapses because then they'd actually have to do something useful for a change.
