Jeff Caruso of Network World reviews a year's worth of panicky media reports and picks the top 10 ways Facebook and Twitter are allegedly destroying our lives. For example, a story asserting
that using Facebook and playing computer games will give children rickets. The basis for the claim was more reasonable – spending too much time indoors means you get less sunshine and therefore less Vitamin D, which in turn means you are less able to fight off the bone-weakening disease rickets.
Some writer apparently made the leap that those kids are spending their indoor time on Facebook and, ergo, Facebook causes rickets. In this case, the misquoted professor managed to get the word out that he was taken out of context.
