Excellent point, but the FBI will not actually show any interest in SM--like satan, they prefer that people believe they don't exist (and don't read our messages). Besides, it's a kindergarten algorithm, and I expect similar ones to crop up on websites all over. I bet the world's most paranoid are already rolling their own to wrap their encrypted messages in something light and friendly in their own voices, similar to the messages they usually send. The second generation "personalization" is where it gets really interesting. So in other words, if you're really paranoid, you're not too worried about the feds.
