Study: Las Vegas shooting was Twitter's saddest day ever

NEW YORK - The mass shooting in Las Vegas, in which at least 59 people were killed and more than 500 injured, was the saddest day ever recorded on Twitter, according to Hedonometer, a tool that measures sentiment on social media platforms.
The barometer, which measures the happiness of millions of Twitter users based on their posts, showed an average happiness level of 5.77 on Monday when the deadliest mass shooting in modern US history occurred at a country music festival in Las Vegas.
The previous record low was 5.84 on the day of another mass shooting in Orlando, Florida that killed at least 49 people and injured more than 50 last year.
