I think writing a daily post is one of the best ways to get noticed on Steemit, but there are some very successful Steemians who only do one post a week, or less. Also, when you write a daily post you are in danger of burnout. It's great for a while though.
I think if you post less often, but try to schedule your post for the same time of the week, people will look out for them at those times.
One of the blogs I started about three years ago just got no interest, and after a while I just lost interest myself. It was like talking to a blank wall. The other day I had a look at that that blog, and suddenly there were real people signing up to it and posting comments. There were even requests to know what kind of products I was using (which means I could start earning money through affiliate links). It takes so much longer to make an impact on the Google-dominated internet than it does on Steemit. I don't know if I can be bothered getting that blog going again though!
