Writing this post as rationality case study
I think this is a trap a lot of blog-posters and similar fall into. You're not motivated by writing itself being fun, you're motivated by the desire for attention. The former you can control, the latter you cannot.
The boring answer would be "keep writing, 10% of the posts get 90% of the views, maybe you'll get lucky next time". This is kind of true but also kind of gambler's fallacy.
If I were you, I'd decide on a specific number of further posts to write and if nothing gets any traction, I'd simply stop and move on to something else. I don't know if that's possible for you, maybe your addiction is more debilitating. But those are my 2c.
