I will definetely do not recommend to use this app, it is app created by third party, not by original Bitcointalk creators. So you risk that you will loose access to your Bitcointalk account!
I agree with you, because so far there is no clear answer what will happen with this application. I think that such an application would be a great solution for people who spend a lot of time here, but this application should be created by the developers of this site or at least in cooperation.
