I like to call such a list a "wall of shame", and I have my own over here: http://jeffrey.io/wall-of-shame.html

What has helped me over the years is that I view tech as art, and so these projects are only market failures. Your growth as a technologist is manifest, and it's important to see side projects as a form of practice.

If you can move past the failure label and see everything as successful at something, then you feel a whole lot better. A discipline that I have had for decades now is to write a postmortem on why I believe a project is a failure because that crystalizes my learning.

My history helped me excel as a principal engineer which put me towards an early retirement where I can now focus on my ultimate side project: Adama ( http://www.adama-lang.org/ ) which I am turning into a new kind of PaaS thing.

Here is the crazy thing: I already know that I'm making several mistakes as I have no customers and no one asking me for anything. This is an exceptionally lonely way to start a project as the OP and others have noted, but I'm enjoying it well enough.

I'm sure the name is tongue in cheek, but of course your 'wall of shame' is very much a wall to be proud of, you've been prolific and learned much.
