Yes, I have written a few hubs that I just don't feel are good enough to get any traffic. I will publish them, I will just redo them and do some SEO work on them before publishing.
Particularly when I was new, I wasn't too clued up about how it all worked so many of my initial hubs didn't do so well, so that made me hesitant to publish some of the ones I felt were weaker. Plus some of the subjects I initially picked to write on don't get much traffic.
I think that as long as the quality is there you should publish and it is my goal for the remainder of the year to publish everything I have written. The reason for this, is that I have made the effort to write them and research them. Also, I have no idea what is going to prove popular. My two most popular hubs took me completely by surprise, I almost didn't write my most popular one as I just didn't think anyone would read it (how wrong was I)
