My guess it is a vicious circle. Someone posts a story, no feedback. Two years worth of stories, no comments. Either no one reads what's posted or no one cares for the content. Either way, why write a story on the Trashcan theme if no one reads it? Sure, there's art for the sake of art, Ars Gratia Artis (the MGM logo), but if intrinsic value is the only satisfaction, then why post the story at all?
So what changed? I've followed the Gromet website off and on since its beginning. Like any amateur endeavor it changes over time. Not commercial, so no need to pander to smaller audiences unless it's a personal preference. I'm sure my stories aren't all that popular, but I'm not too concerned about competing for readers. I do rite purely for the fun of it, and if my fans (both of them) enjoy it too, so much the better.
However, I focus on subject matter that interests me, or on rare occasions I stray far afield for the challenge of thinking out of my inch wide, mile deep rut. Those who are in it for the glory of writing trashcan stories appealing to thousands of readers, well, perhaps they've moved on to website more suitable to that approach. Now breathing life into a dead story category, that might be a challenge...
