I do them bi-weekly, but it still takes up a lot of time. However, if you don't do them, people will feel like they're not being heard and they have no scheduled semi-informal way to communicate with me. So I will never hear their worries or concerns, I don't know what they're struggling with, I won't hear their ideas for improvements, etc. I think they're super useful, especially in a mostly-remote context.
