This is an excellent article and brings some thoughts into my mind.
I'll discuss videos first. I posted some videos by uploading them to YouTube and then copying the link in my Steemit post. This seems to work great and I don't know of any reason to change this. There may be a reason or two; I just don't know what they are.
Also, as I read this post, I began to ask myself "what are Steemit's goals?" My goal for coming here is to have a place where I can interact in a positive way with other content creators. I like the idea of getting paid for my music and short stories but it is not my main motivation. My motivation is to interact with other artists, get inspired by them, get advice from them, and maybe share a part of myself with the world. So far, mission accomplished.
To get to the point, Steemit should outline it's goals, develop metrics to measure where Steemit is at with regard to those goals, and then develop strategies to reach the goals they haven't met yet.
Finally, I enjoy the longer posts. I take time to read them and process them. I can do this on Steemit because I don't have all the pop-up distractions that I get on FB.
I appreciate the post. It provides good insight and ideas for an original content provider like me.
Thank you.
