The rapid rise of Twitter and other social media tools has enticed many members of Congress to personally use these services. Such waves of technological adoption are comparatively rare in Congressional history, leaving us with little knowledge about why some members of Congress adopt new technologies while others do not. We find that Twitter adoption and use are relatively difficult to predict. Members are more likely to use Twitter if they belong to the minority party, if their party leaders urge them to, if they are young, or if they serve in the Senate. Surprisingly, we find that electoral vulnerability has little or no effect on Twitter adoption or use.
