It powers nodejs.org. It has 7.8k stars on Github.
It was installed 5x as much on NPM in the last 4 months as it was in the previous 5 years. https://metalsmith.io

I've been doing a lot of outreach to individual users, websites, and related Github projects, yet community involvement is hard to get by. If you value copy-left or free open-source software and are interested in bloat-free nodejs static site generation or build pipelines, please reach out.

I have a full-time job and am thankful for any help, be it feedback on the Gitter chat: https://gitter.im/metalsmith/... maintaining one of the 15+ core plugins, creating starters or writing blog posts.
