10.All around the world,more and more people are donating their time to take part in online volunteering projects.What motivates them to help strangers without expectation of money or even thanks?
Radha Taralekar helped teach Imelda how to protect herself from HIV,though the two have never met,and neither knows the other's name.From her home Mumbai,the young woman took several weeks to write a guide especially for Imelda-who lost her children to HIV/Aids in Uganda.Taralekar received no payment for the job.Taralekar is one of a number of talented people who regularly donate their time online.But what is driving them to help total strangers,while asking for nothing in return?For Taralekar,the project gave her the chance to use her professional experience."I want to serve people with my medical knowledge,"she says.
For some,the inspiration to volunteer online was far more personal.After losing his wife to cancer,Tony Selman spent many hours online helping Cancer Research to collect data on the disease."Seeing how painful she was when my wife was dying,I determined to help scientists find a cure for cancer,"he says.
Interests and hobbies are also one of the factors.In 2011Sam Luk,a designer,joined other online volunteers to try to help the police solve a murder case.Twelve years earlier the body of Ricky McCormick had been found killed in a field in St Louis,Missouri-the only clues being two encoded (被译成密码的) letters found in his pockets.Unable to decipher (破译) the codes,the police posted them online,calling for volunteers to help them make sense of the messages."I'm interested in patterns and I love Sherlock Holmes,"says Luk.He spent hours every week trying to decrypt the notes,but the case remains unsolved to this day.
For writer Clay Shirky,some large online volunteering projects benefit millions of people,giving him a sense of achievement and generosity.He helps write Wikipedia,the world's biggest encyclopedia (百科全书),which is written entirely by people willing to donate their professional knowledge without any reward.
