Crack in China's firewall turns Obama page into freedom forum

Chinese Internet users taking advantage of temporary access to Google's social networking site, Google+, have flooded President Barack Obama's page on the site with calls for greater freedom in the world's most populous country. It was unclear why Google+ was accessible for some users in China for part of the past week. A Google spokesman said the company had not done anything differently that would have led to the access. Some Internet users said they were accessing the site via mobile devices, suggesting censors may have overlooked certain mobile browsers.
