awesome article, thanks for that! I think finding your niche is a big thing but not absolutely neccessary. I do not really have a nice and I just post the stuff I am interested in and what I love doing. So you will find my art, photography, drone videos and all the creative stuff on one side, but you will also find scientific articles that I write about the topics I am interested in. A niche is a nice place to start but I feel like suprising your audience is a good way too. Anyway, thanks.
