Daniel Radcliffe
It seems that there is no magic spell that will work on one of our favorite British actors for him to agree to use social media. Radcliffe said during an interview that it would be crazy and unhealthy to read comments about himself online. For a moment he thought about opening a Twitter account, but he immediately went into full honesty mode and said that if he had done so, we might be waking up to read the paper every day and find stories of the actor picking fights with random strangers who criticized him on social media.
I think they mean that craving attention on social media is more of an American thing. If they don't, then I do.
