IS the weight of expectation weighing too heavily on some competitors, and even fans, in London?
That was the question after a dramatic day three of competition that saw police arrest a 17-year-old for an offensive Twitter post against British diver Tom Daley after he and Pete Waterfield bombed what seemed a certain gold in the 10m synchronised diving.
The Twitter user accused Daley of letting down his father, who died in 2011 from brain cancer. That incident came on the same day Australian swimmer Emily Seebohm burst into tears and said she had let her parents down after finishing second in the 100m backstroke final.
Seebohm had not figured in medal discussions before the Games, but became the shortest-priced favourite in any swimming event in the first three days after setting a new Olympic record in her heat.
The 20-year-old later said the fact she stayed up late reading comments by well-wishers on social media may have contributed to her slower swim in the final.
"I've obviously got to log out of Twitter and sign out of Facebook sooner than what I did," Seebohm said.
"When people tell you a thousand times 'you'll get the gold', somewhere in your mind you are going to say 'you've done it'."
The biggest flood of tears, however, came at the fencing where South Korea's Lam Shin was inconsolable after losing to German opponent Britta Heidemann.
Shin was the winner when the clock stopped, but officials reset it, added on one second and in that time the German scored the winning point.
The South Korean sat on the stage, sobbing uncontrollably, while an appeal was lodged. Shin broke down in tears a second time when the appeal was dismissed - almost 75 minutes after the bout ended she was led off the stage.
