The team behind the Caddy secure-by-default webserver have written a blog post on their experience with MOSS:

The MOSS program kickstarted a new era for Caddy: turning it from a fairly casual (but promising!) open source project into something that is growing more than we would have hoped otherwise. Caddy is seeing more contributions, community engagement, and development than it ever has before! Our experience with MOSS was positive, and we believe in Mozilla’s mission. If you do too, consider submitting your project to MOSS and help make the Internet a better place.

Always nice to find out one’s work makes a difference. :-)
