The issue is privacy settings. To summarize the above article, Querki allows users a lot of fine-grained control over security, but to make it usable we're going to need to sum that up into a few easy-to-use options: you pick one of these, and then tweak the details if you care. I expect relatively few people to do much tweaking.
The question at hand is what the *default* option is when you're creating a Space, Public or Private. For reasons I describe in this comment, I don't think we can entirely duck this decision -- at the least, we're going to wind up subtly influencing user choice, so I'd rather do that deliberately instead of by accident.
So the main question is, when you create a Space, which of these options is the default (or at least, on top of the list):
- Public: The Space is (mostly) publicly-readable and commentable, a la a typical LiveJournal.
- Private: The Space is (mostly) not readable by non-Members, a la a typical private Facebook group.
Closely related and still important: should we be explicit about this default, or should we require that the user creating the Space make a decision? (That is, should one of the radio buttons be checked initially or not?)
Opinions solicited, at least in this quick poll. I'm very much on the fence here -- it's a less easy issue than it looks at first glance. Comments and thoughts also welcomed...
