This document provides an overview of a lecture on using social media for scientists. The lecture includes two parts: mapping current social media use and how science is using social media. It discusses tools for curating and sharing information online, developing an identity as a digital scholar, and metrics for measuring impact beyond citations. Social media allows scientists to engage broader audiences, collaborate openly, crowdsource funding, and disseminate findings quickly. While challenging myths, the lecture argues social media's benefits outweigh costs for advancing research conversations and visibility in today's digital landscape.
