Love the fournova logo, something about it is just really aesthetically pleasing. It looked like an airline logo to me before I realized (from the more colorful logo for the app) that it was a control tower. Great job. Who designed it?
The app... I don't know why, but I never realized that I needed this. It's a private GitHub for self hosted repositories, duh. Will definitely give it a try.
If that's what you're expecting you will be disappointed: it's simply a Git client, a (very nice) GUI alternative to the command line.
I really like GitHub for browsing and reading code, something that you don't get with self-hosted repositories. That's really the feature that I was thinking of. Obviously there is a great deal more to GitHub than that.
I read the entire article and have no idea what your app does or why I should care.
