I often use writing (and photography) as a relaxation and meditation exercise, and to that end as often as not I am writing for my own benefit as much as I am writing for "public consumption."
As much as anything, the important thing (at least to me) is to use community tags appropriately; for example I would never dream of tagging LeoFInance with a post like this, even IF I might earn a few tokens. Communities are a way to stream content and aid in the content discovery process.
Same goes for not posting certain content in niche communities. It will make it harder for others to find the content they actually subscribed to if it gets flooded with other kinds of topics. We should be mindful in what we do I guess :)
