Probably. I've also been in Open Source around 20 years, UK based. I don't recall hearing about Framasoft before.

Opensource needs to somehow unify. With more awareness of open-source developers and projects between each other, we could maybe make some real difference.

Opensource devs and maintainers could all from each other and collaborate together.

Damn... I sound like a business person that throws around words like synergy.

Framasoft is more about spreading the word than actual development, though. It is not that surprising it's little known abroad.
