A few days ago, someone I follow asked the community for help maintaining his side-project, 512kb.club. This got me thinking. There are loads of maintainers out there feeling burnt out, but they can't abandon their project since people are depending on the project to be maintained. In an effort to combat this, I built a website that lists projects looking for new maintainers. It's still quite empty and has some rough edges. Any feedback is very welcome!
