If not QQ,there will be another software instead of it,like MSN or skype,QQ comes from ICQ,just because our Chniese is really clever and make ICQ to QQ. In the future,it must has another free sofeware will instead of QQ,if QQ is not so good for us. That is the marketing,there has willing there has product.
I think there is no right or wrong with the net ,its depend on us how we use it ,if we make good use of the net to study and conection with friend, its good for our life,however ,if you are just indulged in the net game and some otherthings , that's not useful to our life.So it just depend how you use it.
I think QQ software does great help to our work and daily life.I can not imagine what a mess life it will be without QQ.
so,I believe that the advantage outweigh the disadvantage.do you agree with me?
