The story of Doozer is a classic example of how not to steward an open source project.

It was released by two Heroku engineers who promptly completely abandoned it. By completely I mean did not respond to any communication whatsoever for a year or so, despite a very active community that had sprung up around the project in terms of users and forks. I don't begrudge them their lives (or whatever drew them away), but there were people/companies willing and able to take over maintenance, but not even that happened. It probably would have taken just a few hours to hand over maintainership. Instead, just radio silence.

Eventually there was some movement and the most active group of fork maintainers were given commit access, but by that time any enthusiasm over Doozer was long dead and gone.
