A lot of times with side projects I wished I had gotten feedback early on, before I spent a lot of time on an inefficient direction. I wonder if people wait too long to publish something before it is fully polished, then realized that the polishing wasn't needed.
I'm interested to see things that people would have never published otherwise. I know a lot of my projects never make it to a published phase, but I still would have been interested in knowing the general reception. Please drop your projects here!
