Can anyone with experience at Google actually explain what's going on here? Assuming that social apps roll up to the same VP or whatever -- shouldn't there have been a decision long ago to simply their app offerings? I can understand separate orgs wanting to establish their turf by proposing a new app but isn't a leader there to stop the madness.
