Web2.0 is not simply an extension of earlier trends on the internet.The reason is because people needs a bigger market to run the business,and they want to reduce the cost,but make the profit.Web2.0 is a good platform for all the people to exchange the information and most of them are free.It is a very important reason that Web2.0 is becoming so popular.Another reason is because Web2.0 is not only a platform for people to find what they want,it’s also a platform for people to post the information which may satisfy the people.A good example is about Facebook.
Facebook is a website for people to make friends and have fun.You can find your old friends through the Facebook,and you also can add some interesting games and information to your profile and all these are free,although some applications said you need to pay money and then you can use them,it’s also not a real money because if you ask your other friends to use it,it means you buy it.It’s quite convenient and fast.
However,not all the new things are good.Facebook with no exception.When you use Facebook for a long time,you can find that much information is repeatedand and useless.It doesn’t like Google,which can search more information and more useful.
And another point about Web2.0 is that the copyright is not as important as before.Because Web2.0 gives many new people a chance to present them through many different ways.It doesn’t like the old way,people need to spend money to do the advertisement,record CD,etc. So at last I just want to say:base on the free information and the cheap cost,copyright is hard to protect and also useless.Web2.0 is very different with Web1.0 is because the purpose of both of them are opposite.Information is not belong to someone any more,as everyone can change it and save it.People only need the different ways to enjoy the information.
