Haiku is getting closer and closer to R1, which is great. But unless we (you..=) know where we want to go with R2, the project will come to a stand-still after R1 completion. Also, if there's no strong will and direction from the core members before R1 completion, there's a risk of branching, which is something we don't want.
So maybe I'm just out of the loop, and there's already a strong vision for R2, but in that case, then all of us "bystanders" are out of the loop, because there's nothing on the website, and the glass elevator mailing list is just a stream of suggestions, no compilation of ideas or something cohesive.
