"Grayson Allen's legs again a national topic, which is entirely his fault"

Unless you live in a family of Duke fans like I do, you might not care about the Grayson Allen contretemps or even know about it. But here's a CBS report on the most recent event. The reporter writes:

I'll be honest: I had Duke-Boston College on television Saturday when the incident occurred, and I didn't even blink. Perhaps that's because I was also on social media and not totally focused. Maybe it's because my eyes are bad. Either way, the point's the same. I didn't notice it in real time. And neither did any of the three officials. 

So why did it become a huuuge deal? Because somebody put the video on Twitter. 

I'm not anti-technology. I'm not even opposed to Twitter. (For somebody who is, see "It's Time to Kill Twitter, Before It Kills Us".) I just think that journalists and writers of all kinds should devote less time and attention to a tiny, tiny number of folks who sound off on Twitter. Why does our national conversation have to be driven by them?
