It's alright, Yahoo audience probably haven't heard of Facebook yet anyway. </sarcasm>

In all seriousness though, this is a good thing. FB login has become so prevalent, that not having it hurts more than it helps. At the same time, they used to change APIs so often, that keeping it working was a royal pain.

Although it's much easier to implement these days, especially with services like http://hull.io, it's yet another part of one's site/app to worry about.

Good for Yahoo!
