Former president Nelson Mandela need only check the internet to find out if the world still cares about him, with messages of goodwill ticking over on social network feeds. News websites filled the information vacuum on his health with invitations to post a message to the political icon. Mandela was admitted to Johannesburg's Milpark Hospital for “routine tests” on Wednesday.

After a recent report from his friend Anglican Archbishop Emeritus Desmond Tutu that he was frail and a hoax over his death, media have converged on the facility, ready to send out any information on one of the world's most loved and admired people.
