Good point. Here's the quote from the end of the article:
"These all signal Newmark and Buckmaster's wariness about what humans, including themselves, might do if given the chance. There may be a peace sign on every page, but the implicit political philosophy of craigslist has a deeply conservative, even a tragic cast. Every day the choristers of the social web chirp their advice about openness and trust; craigslist follows none of it, and every day it grows."
