I tend to drop in to read some of the public discussions, especially 'The State of the World' every January, ever since that started. I haven't ever paid to join, but if I ever get around to fleshing out some of my writing, I intend to make the effort. It seems to be of most use as an authors group.

edit - here's a link to 'The State of the World, 2019' - https://people.well.com/conf/inkwell.vue/topics/506/State-of... - it should give you a bit of an idea of the kind of community they have.
