The trust model is confusing, yes. It's not completely transitive - I can't see all photos of your friends, only photos that have you in. If you want an LJ analogy, it would be like me posting my photos friends-only, then you taking the ones that were of you and posting them in your journal, also friends-only. Which is precisely the sort of thing that's likely to happen if you get too restrictive in your security model. The facebook way is certainly confusing, but I think it's quite hard to think of a way of doing it that would satisfy more people.
And yes - parties are usually organised using the facebook
mechanism. Group membership helps with this, because you can invite all members of a group in bulk.
