I shared some advice in our work chat today:
If you DM a person you have one person helping you. If you ask in a group chat, you have the whole team collaborating.
If you give an answer in DM, you help one person. If you give an answer in a group chat, you help the whole team.
This isn’t a 💬 (quote), but a reflection of my own experiences working on highly collaborative teams and open-source projects.
