Most of our users aren't active on these social media platforms and don't receive news about GrapheneOS beyond our release notes. Hundreds of thousands of people use it as a daily driver without closely following the project. We plan to reduce our dependence on these platforms.
We'll be extending our Info app with a News section. It can have configurable categories so people only see the parts which interest them. We could also use the Info app to provide a way for people to volunteer to help us with categories of tasks and receive alerts about those.
@GrapheneOS I like this.
