It came from the Internet and, some say, is going to destroy modern civilization as we know it. No, it’s not spam. It’s Netspeak. Also known in some circles as “L33t speak”. Of course, not all people think that Netspeak or L33t is going to destroy the world, although many think that it is rotting the brain of the millions of young (and not so young) people who are “speaking” it. But no longer a passing fad, some experts say that L33t (or “l33tspeak”) netspeak is here to stay.
