Great- this means that everyone needs to start taking OpenID seriously. I'm not sure what incentive there is for Facebook to join the OpenSocial movement since, given enough time, Facebook Connect could easily become the standard open login protocol. If Facebook's goal is to integrate OpenSocial into Facebook then they could have skipped a huge headache for themselves and developers (in the form of a herky-jerky start) by simply going with OpenSoc from the beginning.
