That's all well and good, and I understand the point, but it does't appear to apply to PadMapper.
Personally, while I'm not a big fan of Craiglist's UI, it's stretching it to think that PadMapper would be classified as "such enormous public good" simply because a small subset of total Craigslist (and Internet) users (most likely in a small subset of American cities) are fond of it.
