Internet...Angel or Devil ?

Internet is the social network. Many people use it to connect each other. You can have fun with many games in websites. Moreover, you can chat, post and write any note to your friends on their blogs or Facebook. This big social network is widespread to all over the world. I'm the one who have my own account at Internet such as Facebook, Hi5 etc. These networks' good point is extensive. I can connect to others easily. I and my friends can share stories and pictures together even we live in different countries but, I know its disadvantage point too! In Internet network, everything that you posted is not private anymore because everyone can link to it. This is a concerned problem for some people. I heard that some companies check their workers by their Facebook. If you or your friends post something that is shameful or something that can cause to the work. The company can fire you anytime, so you should be more careful to the stuffs that you want to post or set private mode to them before. Internet is a two-edged sword. It is a fabulous thing but, if you do not beware, it can also harm you any time.
