Why study digital culture?

I think a digital culture is very important for us to understand and know all developments of communication technics in our life, we can take inter net as an example which is a huge store of information for everyone all over the world also it can help students in their studies by researching on reliable websites to find the articles, journals and reports that are related to their researches or studying cases. The internet offers spaces for universities, authors and publishers to publish their researches, books etc.            

I have a good example how to use social websites to change the fate of peoples as Facebook how to contributes to Arabic revolutions in Tunisia, Egypt and Libya and how to cover all the events in these revolutions and how to change public opinion about them to support the people who are looking for freedom and democracy.

In conclude the digital culture surround us from ever where like shopping on line by using digital personal banking details to make contracts to pay bills to work online. We have to learn more about digital culture to be involved and familiar with all developments.
