This is purely based on personal experience.
I think it's hard to use stories as net promotion tools, unless you're really terrific, you're already famous, or you do a hell lot of promotion on social media etc.
For starters, it's hard to do SEO for stories. A lot of SEO plugins would downright put fiction style writing as SEO unfriendly and unreadable.
Not to say you shouldn't try, though. But you probably should use stories posted here as a complement to your other promotion, rather than a full tool itself.
