Do whatever works for you, friend. If you don’t have the time or don’t want to start/run a community, then you don’t have to. Nobody is forcing anyone either way, but if someone wants something to change, then someone will have to do something about it for that to happen.

In this instance, we can engage with the platform through interacting, posting content, and creating and supporting communities. Setting up and running a community is another option that is available to the original commenter, and is one thing that they can do to fill an existing gap that they see. Whether or not they have the time or energy to do that is up to them.

Take care!
