My take is Engadget had a trusted source and ran with the story. They are often first with this type of news. The biggest surprise was the impact they have on the market. When a blog can affect $4 billion in Apple stock, that's amazing. This site certainly doesn't impact stock prices, but still the same I want to be sure we label all stories correctly. Going forward, there will be a new category for rumors. For example, we recently ran a story regarding a potential release date of June 29th (which I still think is going to be the launch day). That story is speculative in nature and would have been put in the "rumor" section of the site if it had existed. In general, I've tried to keep my sites free of rumors. That being said, many of them turn out to be true and are "newsworthy". EI is a year old. Without rumors, there would have been nothing to report all of last year.

This new section will allow reporting on rumors and more importantly carry a label designating it as rumor.
