Well I have to admit "I didn't know".

Before I watched video "Did you know? version2". http://www.youtube.com/watchWell I have to admit that I didn't know a lot.
I didn't know since computer had been invented, the world is changing by this incredible masterpiece every second. Jobs, environment, social communication, academic research, and so forth are changed by this.
And thinking about it with teaching foreign language, how to use the technical tools appropriately is still a very important issue for every teacher.
