My son Paull turned 25 on Thursday. I rang him from my mobile whilst walking the dogs along the river here in Sydney - he took the call on a train heading to Philadelphia. Paull and a friend have used their September birthdays to raise money for a charity that builds wells in Ethiopia. Between them they raised around $4000. How did they do it? Using the tool of their generation,social media, specifically Facebook and Twitter. I truly believe that the future is in good hands with these fine young people.
