In this society crowded with information, people can freely access to any kind of information. Intellectual property seems to unimportant. Many people even don't aware that they steal intellectual property from others. Is this a definite trend or do we have ways to protect authors?

With the development of technology, more and more people can join the media and become reporters. However, the rise of citizen journalism also has revolutionary effect on different kinds of careers, such as publishers and other aspects of news and sociey.

Participatory Culture is a culture that everyone inside the society can talk, share and control the media. People with loud voice and much money have the equal opportunity of joining in the culture with people with nothing. This is an ideal situation. In the article, Aaron Alan Delwiche and Dr. Jennifer Jacobs Henderson express their idea on Participatory culture. They think that people should join the culture and join in efficiently. People can not bully on minority or hurt others. On the other side, it is more harmful not to join the culture. I think they are right to a large extent. However, participatory culture is an ideal situation to a large extent. People can not achieve equality on the social media

We are now in a world with new media, such as Facebook, Twitter and so on. These tool spread knowledge and information. They help people to work more efficiently. However, on the other side. There are also some false information on the internet. Some people may deliberately post some information to hurt others. It will hurt people.

The Website helps people to define their digital identities and then control their identities. I think it is useful and necessary. People always post something online and then don't know what the effect is. All these information online becomes their identities. However, the information may hurt them in the future if someone bad exposes them in a different way and in a different situation. Many singers and artists suffer from this kind of thing. So, i think it is useful to tell people how they can create a appropriate digital identity.

People have a digital identity to surf on the Internet and get access to different kinds of information. Yes, there are a lot of good resources online for people to know and to learn. However, during the process, people's privacy also takes the risk of being viewed by others. On the other hand, everyone also has a chance to see others' privacy. So, is it good or bad to have such a digital identity. I think it is good and people acquire much more benefits than the risk they take.
