People had jobs before doing youtube videos for a living.
I don't think Tsu should be seen as a way to make money (at least not in a near future) but as a way to get rewarded for the content you produce. The same content which makes the value of Tsu.
Take Instagram for example, talented people post beautiful pictures which add value to Instagram. And yet they only are rewarded with likes/comments. Tsu tries to fix this.
I don't plan anything since I'm not affiliated with Tsu =)
I don't know if they thought about it but since their goal is to give back advertising money to users, doing so won't harm anyone other than the user who referred you.
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
From all its (future) advertising revenues, Tsū will keep 10% and give back to its users the remaining 90%:
* 50% goes back to you directly
* 50% goes back to the people who have invited you, such as the person who invited him gets 33%, the person who invited him/her gets 33% of 33% (~ 11%), the one after that 33% of 33% of 33%, etc...
