Craigslist is an evil monopolist that literally wastes millions of hours of its users time every year through the enforcement of shitty UI (if the amount of money that I save using padmapper is typical). They get a good reputation for some bizarre reason because their CEO is an anti-capitalist, but they are still evil for holding back innovation.

A human lifetime is about 700,000 hours. Craigslist is the moral equivalent of a serial killer.
