I've been using Booklet for a few weeks now in beta form as part of a small, private community.
It's *nice*. This is a tough space, and success will be hard. But if you want to give your community its own space, if you value thoughtful, human-centric (calm?) design and delightful experiences, and if you don't want to force people to master a complex, arcane tool, then Booklet should be top of your list.
