This looks like a clever hack of the Twitter implementation of the Player card and not the intended use. The stream and content type attributes both are empty, for example. Does anyone know if this sort of implementation is what that card is supposed to allow?
I say "sadly," as if this is the case, Ribbon have just made every other developer's life that bit more difficult.
I really hope they haven't been that underhand, though.
Maybe it's just an old screenshot though. I don't know.
