BOSTON (CBS) – What a gift the Internet is, wouldn’t you say?

It gives us the ability to share stories with a mass audience, and make our reactions felt, exposing lies and shaming worthy offenders.

There’s strength in numbers, and that was evident yesterday when a Harvard Business School professor named Ben Edelman was brought to heel by social media for venting his spleen at a Chinese restaurant that overcharged him for his dinner.

Edelman had used an online menu to order takeout from the place, but when he checked his bill, he’d been charged $4 more than he should have been. When he complained, a spokesman for the restaurant acknowledged that their online menu was out of date, and offered to send him the new one.

Understandably enough, Edelman wanted a refund. The restaurant offered less than the overcharge, and things escalated quickly from there, with the professor – as academics sometimes do, hello there, Prof. Gruber – quickly lapsing into arrogant legalisms that rightly struck those who read the email exchange on as obnoxious.

And the power of the social media mob was unleashed on Edelman. Obscene t-shirts dissing him were on sale by midday; Twitter tore at his flesh. By late in the day, he was issuing a prostrate apology to his victim.

Lost in all this was the fact the Edelman’s complaint to the restaurant was valid. A bait-and-switch is a bait-and-switch, and it’s wrong, a fact the mob ignored in its rush to string him up.

The Internet is a great tool, alright. But one thing it can’t do is make people think before they vent.
