Well, no one outside jolla/mer knows the bigger picture of that whole mer / jolla / nemomobile / other derivates thing. Kinda hard to make decissions with non existing facts. A community driven effort would be best, but only if the community has a break even size where most stuff got handled by the community itself. If it's only a small community, a commercial driven platform (with community support of course) would be best.
I'm afraid that if this kind of things gets delayed, Jolla will build its own site, and Mer/Nemo its own, and Cordia its own, and the chance to unify the talking arena will be gone.
