Ethan Zuckerman when asked about his thoughts on the impact of blogging in Africa gave the following reply
"I don’t think blogging in Africa has had the same huge effect as it has in say North America yet.

In Africa I believe this is less of an issue as there is less corporate ownership of news media."
