"As any other social media website Twitter know a lot of things about you, thanks [to] metadata," a French security researcher known as X0rz wrote in a recent blog post. "Indeed, for a 140 characters message you will get A LOT of metadata—more than 20 times the size of the initial content you typed in! And guess what? Almost all of this metadata is accessible through the open Twitter API." To demonstrate that, X0rz wrote a Python script called tweets_analyzer, a command-line tool to tap into some of Twitter's vast metadata that may not be accessible from the standard client.
