CNET: A study conducted by Facebook’s number-crunchers, titled “The Not-So-Universal Language of Laughter,” looks at the different ways that Facebookers express laughter. The researchers claim they looked at one week’s posts and comments to see whether there was democratic agreement about how to laugh in social media. Some 51.4% said “haha.” Next was the laughing emoji. But the big news is that “LOL” is laughably rare. A mere 1.9% of these Facebook users used this once-admired expression. The researchers did say that LOL is still popular in the south. The Midwest is very fond of emojis, however.
