I have a couple of goals where Pixelfed serves me well. I want to improve my photography, as well as get outside (away from all my screens) more. So I've encouraged my OCD/hyper-fixation to post daily. To improve something, I think you need to have criticism of some type. I measure that in terms of likes or reposts on pixelfed. It's not perfect, but it is some validation. Sometimes people post comments, but that's unusual.
I prefer Pixelfed since I don't want to feed the Meta beast.
