There’s a decent interview with Craig’s List founder Craig Newmark in yesterday’s Chron, telling the history of what is, in my experience, the best community website in the world. (As a recruiting tool, Craig’s List smokes HotJobs, Monster, Dice, etc.)
It’s really just a living proof of Metcalf’s Law. There’s nothing technically wonderful about craigslist.org; it’s a low-tech bulletin-board / classified ads system, with a UI straight out of 1998. The value is in the reach. Post an ad there, and you’re practically guaranteed a response.
The Chron interview didn’t tell me anything I didn’t already know, but it’s reassuring somehow to see that the personality of the website matches that of its founder, which I’m sure is entirely by design.
