Social networking, email and other 'new' technologies are often cited as barriers to forming genuine and meaningful human relationships. So I was interested to find this story on BBC today, about a woman who found her long-lost son through Facebook. Avril Grube from Poole in the UK had not seen her son, Gavin, since he disappeared with his father in 1982. Her former husband had taken the boy to his native Hungary. She and her sister had been searching for Gavin ever since, and her sister finally found his Facebook profile through an internet search engine. Eventually, direct contact was made, and Avril and Gavin were reunited. Now, apparently, they are happily catching up - face-to-face, at last.
