On the Internet, People Say: "Huh?"

New York Times columnist David Brooks opines:

"On the Internet, the long term doesn't matter, as long as you are blunt and forceful at that moment. On the Internet, a new persona is just a click away. On the Internet, everyone is loosely tethered, careless and free. Dean is the Internet man, a string of exhilarating moments and daring accusations."

Does anyone have any idea what he's talking about? I particularly like the assertion that "(o)n the Internet, everyone is loosely tethered, careless and free." This is stuff you would give a seventh-grader back for re-write. It's embarrassingly stupid.
