I see the community support for SN. As long as the devs who will be implementing the solution are onboard, then I'm onboard.
Could we share a roadmap? It does not necessarily need dates, yet.
I suggest running an agile type project management style. Perhaps make a larger roadmap, but only give dates for specific goals that can be completed within 2-3 weeks. Choose your sprint cycles 2 or 3 weeks. So only commit to any work for the 2-3 weeks and don't worry about dating the roadmap beyond that.
GO ahead, please make a roadmap. Devs are busy coding.
As much as most of us here don't like the word " Roadmap", it could be used constructively as an informative tool for us and attract more people to this project as long as it's not being used for pushing our devs into a time restrain . IMHO
