Interesting but not surprising. Many people, including hackers, just don't think very much when picking a password. I have used foreign words and phrases for years and never had a problem, but one never knows when someone will figure out what one is up to.
The Internet can be a bad thing in the hands of the wrong people or even the right people for the wrong reasons. I think one of the things that has potential for causing more trouble than it has already is the idea of a 'social' network. People are so used to private communications that it never occurs to them that the Internet is a broadcast medium. Anyone with the proper equipment can sit on the data stream and intercept all of it.
