Craigslist has just about the worst user interface / search / features that I can imagine. I look at craigslist and see a conservative and understaffed company headed by a man with many virtues, but takes a near-religious stance against any kind of improvement, evolution, or change on his site.
I admire craigslist a lot for not exploiting their users. But c'mon, lets upgrade the search/filtering/user experience a little bit! I don't think the users would cry over one new feature every year or so. I wouldn't.
Hm. Better not vaccinate my kid then, since he's more likely to get whooping cough if he's fully vaccinated.
If God had a beard, he'd be a UNIX programmer.
