It seems to be the case. I was encouraged to do a lengthier food article after being upvoted on my previous writings. I prepared a meal with photographs taken all the way through, and wrote a recipe and instructions to make it. It's reasonable to say I put much more effort into making it than in my previous posts (combined). And suddenly it got almost no votes at all. It is frustrating to say the least.
Not sure but it does seem to take the fun out of it. I think I need to re-assess what and how I'm going to write here in the future.
I would say just write about anything you are passionate about. Pour your heart into it and be genuine. Eventually you will gain more followers and score more votes.
