One Killer App

Ian says that wikipedia and Google are the new killer apps. I say no way. I say email is the only killer app in that it does what it promises and is useful to anyone who comes into contact with it. The web, conversely, fails in many many ways…but even saying that is not getting it. Is there any other industry and activity which lacks any real critical analysis of its downside? The teflon effect of the Internet is likely its greatest success.
