I feel badly for the person whose placed got trashed, and it seems Airbnb is doing what they can to remedy the situation - but am I the only one who feels there's a certain risk to be assumed with online transactions such as this? If a girl meets a man on match.com who claims to be single, but after getting into a relationship with him she finds out he's married - is match.com to blame for this? Could they have done more to verify his background - perhaps, but that's also the risk we take. It's an unfortunate incident, but trust me other than hacker news, techmeme and techcrunch (that's where the FT got it from) this is not really headline news, and it's not going to affect airbnb's performance in the long run. On a separate note, I hope pg realizes with 423 comments on here it's hard to make heads or tails of what to read - hopefully the comments rating system will be brought back.
