That doesn't disprove my point. Just because you don't like their approach doesn't mean they don't get points for having an approach. So far oAuth is vaporware and not consistent in almost every implementation yet still effective because it's just an idea.

Because it doesn't really work unless everybody does it the same way.

I disagree. It's not hard to adapt to using oAuth+Twists for a given provider. It's not like it's some secret handshake nobody knows and you can't get into the cult meeting. It's just signing data and exchanging tokens. We don't need a universal standard. We need a universal understanding of the problem we are trying to accomplish and various recommendations for how you might solve it. I think the work on oAuth is already complete.
