This was announced today https://clojuriststogether.org/
It seems to be an initiative similar to https://rubytogether.org/
They collect donations to fund infrastructure (Clojars) and to support the development of key projects that people in the ecosystem rely on.
They are a member project of the Software Freedom Conservancy, which seems like a good indicator that they’re serious about this.
I’m really happy to see this kind of initiative, and I’ll surely be putting in my part.
