The digerati are having fun with the Securities and Exchange Commission’s ruling that US companies can use social media to distribute market-sensitive information such as earnings reports. “Facebook Flap Forces SEC Into 21st Century,” says Forbes.

Not so fast. The US regulator’s decision to drop its inquiry into Reed Hastings, Netflix’s chief executive, who boasted about new viewing figures on his personal Facebook page, is only an incremental advance into the new millennium. It makes sense for the SEC to acknowledge the growing use of social media (I’m guessing more people saw Mr Hastings’ Facebook post than have viewed any regulatory announcement in corporate history), but I don’t think the decision will prompt fearful CEOs to tweet their earnings much more than they do already – and, even if it does, it won’t make much difference to investors.
