I saw this headline this morning in The Star (read the article on IOL):
An sms and social network frenzy saved a Joburg man who was trapped in his car boot after being hijacked at the weekend.
What a terrific story and a great ending for the poor guy who was hijacked. I disagree that Twitter is a truly useful social network for personal sharing but when it comes to social signalling, Twitter is possibly the best tool available. This story just demonstrates its effectiveness.
What do you think?
