Just as an update on the post that I've written a few days ago: it was apparently a glitch on all Google's results:
It does point out that the more people only use one system, the more dangerous it will be if this system starts having problems. And amazingly enough, it's very easy for software systems to have problems (it tends to have more "moving parts" than non-software systems - although I always find bogus the idea of being able to explain software engineering using terms from mechanical or civil engineering).
Anyway, I won't say much more than what the article already says. Errors happen and Google was there to fix the error as quickly as they could.
