Insightful post. The title did, however, threw me off. A graveyard implies death, which we generally associate with grief sadness, nothingness, etc. But but placing projects on GitHub, startups are contributing to our collective knowledge, helping others, engaging in an act of kindness, etc. So maybe a more relevant analogy would be museum, library or (art) gallery? [pedant]
Thanks. Agreed. Gallery sounds like a good analogy, but in this post I was trying to use the term "graveyard" as a good thing. Guess I couldn't overcome the terms' connotation. Modified the title to point out that it's a good thing :)
