On the lighter side… Just found, and thought it was interesting enough to share…? Stock Twits.? Just in case you want an even more spastic view of the markets…? but it might be useful to watch the rumor flow or day-trading junkies.

Also useful is BreakingNewsOn which attempts to identify breaking news.? There are a few news stories, including the passing of Tim Russert, that have supposedly popped up on Twitter well before any mainstream media.
