Young people taking part in the World Summit on the Information Society in Tunis share their hopes and fears.
Moustaffa Hussein, 20, is an engineering student in Egypt. He thinks language is one of the biggest issues facing the net's future.
"The net makes it easy to translate, but all the web is in English and most people don't have the ability to read and write in English. We must give young people more chances to express themselves in their own languages."
