: SSRN-Tweets and Trades: The Information Content of Stock Microblogs by Timm Sprenger, Isabell Welpe.
Abstract: Microblogging forums have become a vibrant online platform to exchange trading ideas and other stock-related information. Using methods from computational linguistics, we analyze roughly 250,000 stock-related microblogging messages, so-called tweets, on a daily basis. We find the sentiment (i.e., bullishness) of tweets to be associated with abnormal stock returns and message volume to predict next-day trading volume. In addition, we analyze the mechanism leading to efficient aggregation of information in microblogging forums. Our results demonstrate that users providing above average investment advice are retweeted (i.e., quoted) more often and have more followers, which amplifies their share of voice in microblogging forums.

via USC Researchers Demonstrate Real-Life Gmail Motion – Slashdot.
An anonymous reader writes "In this tongue-in-cheek video, researchers at the USC Institute for Creative Technologies take playful jabs at Google as they demonstrate their software controlling Gmail with a Microsoft Kinect sensor. The gesture controls are strikingly similar to those jokingly suggested by Google in their fictional Gmail Motion application, posted as an April Fools’ day prank. The researchers have made their software available for free on their website."
