This has a little of the flavor of "Valley Wag" -- subtly slamming innovators for failing to fix the internet/economy/government. Scribd allows people to share content and, lo and behold, people use it to share porn -- just like Facebook, youTube, Flickr...

The author can't really make up their mind as to where Scribd is in error: are they using porn to drive up traffic, or do they fail to have right the disclaimer? Going so far as to ask whether it is "acceptable for a VC backed company to drive growth via porn?", the author back pedals and asks for an "Are you OK with this?" dialogue, though the site already has it. (Maybe that changed recently?)
