I can relate to this. I created several products that I never launched. Now that I look back, I wish I hadn't been so reluctant to publishing them. Granted, I learned a lot but I wish I launched early and often to get over the psychological hurdle. Most people don't really care about your project anyway.

I finally bit the bullet and launched http://www.survivalscout.com in January. It's a definitely whole new set of challenges going from coding to trying to market and sell your project.
