I think you're right. Good idea, but not enough interest to waste your time on. I visited this thread because I was anxious to see what you made, not because I was interested in taking part. My "Thanks" was in appreciation of the idea. If this gave you false hope, or was insulting in some way, I apologize.
As far as how it was presented: a shorter more succinct write up might have swayed those who were moderately interested. However, if you say that no one has shown significant interest, I think you were right in saying it wouldn't have made a difference.
