See the original parent's first sentence:
What is the point of this? I don't want to have to login with facebook at all. .
and then his reply,
Then use one of the other implementations. The problem is it being facebook, not the concept.
It's basically anti-Facebook login sentiment to me. Fine, I respect that. But,
If you use facebook login for your site then you are shooting yourself in the foot if you care about users.
You can't shoot yourself in the foot if your audience of your service can choose. As I said before, people who only offer FB as a login/sign up option is not FB's fault. In fact, any websites that don't offer the vanilla username/passwrod signup & login mechanism isn't FB's fault. So don't mix that issue in any discussion related to FB's new login mode here.
Now moving to yours:
We are hoping they choose not to use the platform _exclusively_ or as a substitute for their own login.
I will take it as you don't want to use any website not providing the vanilla username/password signup-login, right?
So again this has NOTHING to do with FB and its news announcement.
the product we're talking about is offered as an alternative to the real thing (Facebook Connect) and it is what a developer would consider using to avoid writing their own login system.
I am confused here. Do you like FB connect and like it over anyone's custom login system?
What exactly do you and parent want from Facebook's login and from app developers?
