Shortly before 3pm, a single from the CBS operated What's Trending account about  ("Reports say that Steve Jobs has passed away. Stay tuned for more updates.") has sparked a frenzy of speculation about the founder of Apple. What's Trending soon retracted the tweet: "Apologies- reports of Steve Job's death completely unconfirmed. Live on." But big tech blogs like Gizmodo are on high alert. "We realize we're cranking the wheel on the rumor mill by writing this, but we want to settle the question definitively. So we've got our feelers out everywhere, and are trying to either quash this rumor or verify some awful news we've all been dreading," writes Sam Biddle

Much of the speculation seems to be tied up with Apple's stock performance on Friday: down just below 2 percent. Jobs, of course, stepped down as CEO two and a half weeks ago but he's staying on as chairman. Even if he's not the chief anymore, he's still expected to be a guide behind the company. So, it's worth pointing out, that while Apple was down for the day, it basically kept pace with the broader market late this afternoon, even gaining a bit after the rumor started circulating on Twitter. So while the tech bloggers seem worried, stock market investors do not.
