AtomPub in OpenSocial 0.7
I missed this one in my social networking API link-fest yesterday: Google announced version 0.7 of the OpenSocial API, some of the data APIs are outlined in the spec and they're still using AtomPub protocol (just like GData).
I had heard there was some push-back against AtomPub, but I really don't know what is going on because there is no transparency at all in the specification development process. So, who knows, but I really don't think they have time to invent an all new protocol. In fact, they'd better wrap things up tout de suite because Google's planning to go live with OpenSocial on Orkut during the last week of February.
