I am with Dave Winer on this one!
Sometime in November Google is rumored to be revealing their answer to Facebook. Whatever it is it will surely have an API, and will allow Google apps to share the info, and it will, if it hopes to compete with Facebook, provide some access to this data to app developers. But the true measure of their gravitas will be whether they give full control of the user’s data to the user. If they do that, no matter what’s missing from their software, it won’t suck.
