Twitter can have both positive and negative impacts on society. Positively, it allows easy connection with friends and family regardless of distance, and facilitates fast communication. It also benefits businesses by allowing promotion and research of trends. However, twitter can be a distraction, especially for students, and reduce privacy as users overshare personal information. It may also contribute to relationship issues if used irresponsibly. Overall, both benefits and risks exist, so wise use of twitter is important.
