They launched the invitation system less than 24 hours ago.

I agree with the two issues you mentioned but I think the main issue here is the invitation system : you have to share your profile URL to invite people. They should let people invite strangers with a specific invitation URL.

I suppose they made Tsu profiles accessible to Tsu users only to drive adoption. Once they have enough users, it will make no sense to keep it this way.

EDIT: > But then you wouldn't use your tsu account to post personal stuff for fear of your tsu URL leaking somewhere and giving anybody access to your vacation pictures?

You can share private content to your friends & family (requires you to add users as friends) and public stuff to your followers / Tsu community
