Free software is tremendously democratic. Anyone with a computer and an internet connection can get involved – there are no barriers of wealth or social status.

So anyone can contribute to free software, and anyone can start a new project as well. But how do you turn that great idea in your head into a real-life success? The likes of SourceForge and GitHub are littered with now-abandoned projects with barely 50 lines of code, which initially started as grand ideas to create the next killer music player, email client or game. Yes, free software is awesome, but 95% of projects never get off the ground or are abandoned after a few weeks. Read more
