Reflect on what Web 2.0 is

I think Web2.0 is a very influential change in our life, furthermore, it become a big part of our daily life, for example, now we surfing the Internet to read the newspaper rather than reading traditional newspaper and we often read others article on their blog then share our feeling or experiences even some strangers from any country or nation. This is just a small part of the function of Web2.0, there are some practical functions to users, for instance, we can upload some pictures we want to share to our friends and exchange from each other, so in this way we don't have to print those photos out and we can decrease the paper pollution. And I think Web2.0 not just have benefits to the generaion like us but increase large opportunity to business field, for example, they can sell goods by the Internet.
In the end, I think Web2.0 can create more chances to our society and our life and maybe we can get something we desire from the function of Web2.0 even earn some money!!
