“Eric Hellweg wonders if everyone’s favorite want-ad site will join the ranks of eBay, Amazon, Yahoo, and, yes, Google. Hellweg guesses it makes $25 million a year by charging for only 12 percent of its ads. If it ramped up payments on more ads throughout its many-city network, it could hit $100 million. That’s a monster margin for a 14-person staff! And they may even consider going public.”
