The biggest social media time waster seems to be Facebook, where the average American worker spends approximately 405 minutes on the site every month -that’s almost seven full hours. The average Twitter user spends around 89 minutes per month on that site, which means that if you’re like the average worker, then you spend over one full work day a month on social media. While a quick status post here and Tweet there might not seem like much, that time adds up quickly.
