VsnqCXaq9Cp - Am I missing sth. or is G+ quite a dud at I/O? There are a few sessions for publishers (how to add buttons and badges), a lot of sessions on how to add G+ Sign-In, and, well, that's about it. No read API, obviously no write API, no API for the social graph, for search and discovery, not even RSS for the posts.

yep, I was; this sign-in makes it possible for other applications to interact with and via G+ to a certain degree and there are a few other features filed under G+ platform.
