Im offiziellen Twitter-Blog heißt es dazu: "We want Twitter to instantly connect people everywhere to what’s most meaningful to them. In support of this, we will frequently experiment by trying new things, adding new features, and being bold in the product decisions we make. After testing a feature and evaluating its merits, if we learn it doesn’t improve the user experience or serve our mission, we’ll remove that feature."
