Communication in a high tech world

Today, we live in a high tech world. I've never thought about 'Communication in a high tech world'. So, writing blog and thinking about it are very good opportunity. High technology is very useful in our life nowadays. And the world of communication system changes continuously and set of tools are always changing. These days, I think that developing high technology is i-phone. By i-phone having been made, we have a few opportunities of taking communication. Of cource, i-phone is useful and helphul for us. But we can't expand our communication skill much and promote our independence. I think that expanding our communication skill is more important than developing high technology. And we need to communicate with various person around the world. But there are a lot of problems which we should consider because we're able to talk about communication system. And we must think about a definition of communication. I'll make effort to accomplish certain communication skill.
