Call me oldfashioned, but when I heard that a missed penalty in the recent World Cup game between Chile and Brazil triggered 389,000 single tweets in one minute, I did question whatever happened to having a nice halftime cup of tea? But then I began to wonder — if Twitter can generate that much ‘noise’ over a football match, what could it do for issues that really matter, like community nursing, good patient care, or the future of the NHS?
