Kara Swisher:

Social media platforms — and Facebook and Twitter are as guilty of this as Gab is — are designed so that the awful travels twice as fast as the good. And they are operating with sloppy disregard of the consequences of that awful speech, leading to disasters that they then have to clean up after.

And they are doing a very bad job of that, too, because they are unwilling to pay the price to make needed fixes. Why? because draining the cesspool would mean losing users, and that would hurt the bottom line. Consider this: On Monday, New York Times reporters easily found almost 12,000 anti-Semitic messages that had been uploaded to Instagram in the wake of the synagogue attack.
