That's likely accurate, and I tend to forget my usage is probably different than the majority. Probably at least half my time is creating posts. Since my app got a good draft creation setup, I'm able to make posts ahead of time, so when owl news is slow, I already have a few things in reserve. After that is responding, and since my content is fact based, I'll often have to do some research to reply properly. What Lemmy time I have left, I typically just hit Top 6 Hour and leave it at that, so that's how my mind defaults to thinking about sharing content, which as you said, the majority is probably looking broader since their time isn't including that post/reply time mine is.
I feel I miss out a bit on enjoying Lemmy as a whole, but focusing on the post creation keeps me functioning as a content provider. I'm still posting just things I enjoy, which makes it not feel like work. Being an animal comm helps, as if you're there, you like that animal in general, but I'm still finding what I think is best and sharing that as opposed to trying to cater to a more specific audience. I share pics I find I like in my various feeds, I put up interesting facts I read on my own from things I'd be reading even if Lemmy didn't exist, and I like getting questions back, as it makes me learn about things I didnt think about on my own.
I hardly ever get tired of posting this way, even though I'm essentially the only content provider for the comm, save the random person sharing a meme or comic.
