The power of social networking – in this case, Twitter (who recently celebrated its 20 billionth tweet), is at work once again, where Air Canada fixed a terminally ill boy’s wheelchair after it was damaged during a flight. Pressure from Twitter users after viewing appeals from the aunt of 10-year-old Tanner Bawn had reached Air Canada, and not only was the wheelchair fixed, the airline will also send the boy who is afflicted with Duchenne muscular dystrophy to Disney World. Tanner Bawn’s new $15,000 wheelchair arrived at New York’s La Guardia Airport in pieces, so a replacement is definitely in place. It would be interesting to see whether such a thing would happen these days if there was no micro-blogging site or social networks in place.
