The GNU and "L"-ephant in the Room

Nearly a great piece in The New York Times about Google's vertiginous expansion of its hardware platform:

Today even the closest Google watchers have lost precise count of how big the system is. The best guess is that Google now has more than 450,000 servers spread over at least 25 locations around the world.

Great, except for the fact that it misses out one key piece of information: that nearly all of those servers are running GNU/Linux. Kinda relevant, don't you think, John, baby?
