The problem with this approach is that it substitutes good somewhere else for badness here and now. I like craigslist. I like the honesty, the local-ness and the community. It is useful to me. I have never encountered scammers or slimers like on ebay. I've found real people I can related to. Running partners, indoor soccer teams, tennis rackets. They are doing good for the world, and they're doing it directly and sincerely. They can do it better--I like many of the features listed here that they lack--or a competitor will. But I hope they or the competitor retain the sincerity that is a unique gem in today's corpate world.
