TechCrunch: Facebook plans to let everyone unsend messages, will stop Zuckerberg until then.

Facebook retracted his chats, and is now trying to normalize the behavior.

If you post to the internet outside of the courage of your convictions, then you're better off dead if you haven't yet died. Said before, will probably say again. We 'old schoolers' had an unwritten code, you never ever touched your archives after publishing. Zuck's behavior breaks what I consider a moral imperative. Expanding it to others, is just promoting a terrible precedent. What's next, altering history books? Serious slippery slope here. Electronic publishing makes the alteration of past works idiotically simple.
