It's the place where most of the people in my industry (WebGl) seem to gather and showcase their work. Hanging out there too lets me connect with them and has gotten me a considerable amount of work over the last couple of years and allowed me to make professional connection that I would have otherwise missed. I also showcase and advertise my own work there.

I'm extremely careful not to engage in anything related to identity or politics on Twitter. I've added a big list of muted words and accounts (trump, politics, gender, queer, republican, democrat, sanders, etc.). Many of these are topics I find interesting and discussion worthy, but the twitter format doesn't allow space for anyone to formulate actual cohesive thoughts so the result of discussing anything contentious is just people shouting at each other. Once I avoid these topics and stick to discussing tech, twitter is fine.
