QQ is just a tool to help you to communicate with others. but it depends on what the people are on your QQ. I found that I don't like to play my QQ, recently. It seems that you step into a sea of crowd and you still stand at on side of the crowd, and no one notice you nor dare you come on to say hello. As now we are exposed to so many different kinds of technology, there are more choices for us and the most important is how to make the right choice.
TV show, website, sometimes are the best choice. For it is informative, and you can learn a lot from all those things. There are so many nutritions you can dig out from website, and it help to broaden your vision, and open up a new horizon for you. One aspect you may still want to mention is that it helps you to consume the unhappy, boring time.
So many times when we turn on the Computer in a bad mood and turn off it with a clear mind. The much time I spend on Computer the more love are pour into it. Finally, I founf that I just can't live without it .
