I'm guilty of that myself - when l joined Steemit mid July I didn't take it seriously. I was checking the ground and posted a lot of short YT link posts.
Within the time, I had learnt how to write articles. They became long, more complex and better edited.
Now, I finally realised that shorter, engaging, quality articles are way to go.
There is limited attention and time we all can spend for reading posts.
As a long term Redditor, when I first logged on to Steemit, I used it much like Reddit. I shared links, wrote short posts as well.
Like on Reddit, there's always demand for long form articles. The key is to find a balance where both short form and long form content exist and thrive.
