GitShowcase is really wonderful software that can add a lot of value for developers. You could easily sign up and start using. If you are a programmer thee is virtually no learning curve to get over wit. The UI looks great on all 3 platforms its on. They even made the stuff open source.
There is already 117,703 projects showcased. That's a huge number for a new product. It's time you start adding your own projects and showing them off too :)
