Microblogging services like Twitter have changed the world by (1) becoming valuable platforms for sharing information, as seen during events like the US presidential election, (2) replacing many websites by integrating microblogging functions, and (3) evolving into social networking platforms. To maximize their impact, users should post thoughtful, meaningful content rather than complaints or daily updates, and focus on groups, direct messages, and replies rather than all tweets. Microblogging can be a good learning tool if used intentionally for sharing valuable retweets and influencing others positively rather than solely for entertainment.
