Proponents hold their points that social networking sites can make progress to them, while opponents think that it does harm to the users. From my points of view, the advantages outweigh the disadvantages. Here come the reasons.

First, there is no denying that we can come into contact with different people, so that is to say, we can get in touch with diverse culture easily. In addition, to acquire more knowledge and broaden our horizons, we need find more accesses besides books, and social networking site is the best choice without doubt. Last but not least, as the global economy goes deeper, countries all over the world are getting closer and closer, so it is essential to keep communication with other countries by means of social networking sites.

As a famous saying goes, every coin has two sides. Not only should we see the advantages, but also we need be aware of the disadvantages and try our best to attenuate it.

Briefly speaking, social networking site is very useful and we need use it properly. Only in this way can it facilitate social development better.
