Arc Browser is an excellent "what could have been" story. The UI came together amazingly fast, there was excellent posts every week with updates from the project lead, and it felt fresh and exciting. It would be an amazing open source project, but there just not a good way to monetize it. There's no other browser, including newer projects like Zen, with a better ui. I would strongly encourage Atlassian to open source Arc.
