Only "frequency of use" ["daily" + "ever"]
Nothing about posting v. scrolling, etc.
There's many issues involved in surveying people about their media use (vs. surveillance), much slippage, and the metrics can also be confusing.

Just a few hours later, World War I ended. Here’s how it ended for him (from his autobiography, titled, "Now That You Mention It" (1973)) (11/11)

But it was a dud. The German artillery shell didn’t explode. He and the other Marines survived. (10/11)

Then it happened: a bomb landed directly in the middle of his company. Everyone knew they were about to die: “Even if cover had been available, none could have reached it in time. Fascinated, immobile, they could only await the end,” he remembered (9/11)
