Thanks for the invitation to the forum.
My first thought is: I doubt that volunteers with limited time commitment will have the time and the energy to master yet another platform. I mean, having it might be great for people deeply immersed in movement strategy, but most of the folks in the movement are not.
As a result, there’s a risk this becomes an echo chamber for a handful of WMF staff and the few volunteers / affiliate staff devoted to this topic – with limited positive effect for the movement but a lot of time commitment from the Movement Strategy team to maintain it, and in the worst case with more confusion for “ordinary” people on where to keep updated with the most important stuff.
The initiative might still succeed, but I think it’s important for the team to think about these questions and maybe address them more explicitly in communications.
