Obligatory notice to use the tools here. You'll spare yourself so much unescessary pain and frustration, in particular from some of the more active that, know how to game the system (of people and gaining & retaining their attention).
Know what to say, know when to say it, sound like a friend or expert, make use of strategic hashtags but pepper in your real opinions here and there, and go after people down comment because you know the tools have blindspots.
You can make them vanish.
