The Guardian's overage became a crucial source of information for Egyptians themselves once the internet was switched back on. With local media sites often paralysed by the unrest, Guardian articles and the rolling live blog – much of which was translated into Arabic – provided vital detail about the latest political developments...in Tahrir and elsewhere.

Dictators are toppling across the Arab world. What role has the Internet played in their demise? Young people went online to keep up with their friends and youth culture. In doing so, they became politicized. In Egypt, people shared a yearning to oust Hosni Mubarak, but each person was afraid to step forward. Once they saw how many other Egyptians agreed with them, they grew bolder.

Thanks to the rise of social media, news is no longer gathered exclusively by reporters and turned into a story but emerges from an ecosystem in which journalists, sources, readers and viewers exchange information. Journalists are becoming more inclined to see blogs, Facebook, Twitter and other forms of social media as a valuable adjunct to traditional media.

Globally, Yoani Sánchez’s blog, is available in a score of languages and gets up to 14 million visits a month. Within Cuba, though, the dictatorship of Fidel and Raúl Castro has from the start sought to silence her and prevent other Cubans from reading what she calls her “little vignettes of reality.”

The library clearly has reevaluated its role within the Internet information ecosystem and found a set of new identities. Let's start from here: One, the New York Public Library is a social network with three million active users and two, the New York Public Library is a media outfit. The library has become a social network with physical and digital nodes.

I would introduce another working definition that culture is observable worship or work. It is the sum total of the core beliefs expressed through action of one’s perception of reality... Using the above as a platform, the nearly missed opportunity of cultural exchange of the African reality this year is plausibly understandable.

With a long-term strategy in mind, China should learn to fully utilize the Internet. China's "Internet users-based reporters" can disseminate facts to every corner and Internet community around the world through social networking websites and change the misperceptions about China held by the international community.

Last year more than 57 million Chinese traveled outside the country, making the Chinese now the world's fourth biggest spenders on tourism. My uneasiness stems from the fact that Chinese tourists of tomorrow are quickly becoming the successors to the "ugly Americans" of the last century.
