Lol, comments are kind of a rarity on this site, unless you really write gold and make plenty of friends who see your links on their feed. Try writing more stories, you'll get comments sooner or later.
Okay, I went and I saw your story.
It takes a while--but they will come--usually when you least suspect it!
Very few people online comment on stories, and I mean anywhere online. Blogs, articles, stories...ghost towns. People just don't like to say anything if they haven't been invited to say something, then eventually both the writers and readers get bored. E/P QA has been one of the most interesting places I've found online because somehow it actually encourages coherent communication.
