If we assume that Larry and his execs are fairly smart, then what is their rationale for pushing G+? I think they figured that G+ is just like FB, so no one would have a problem with it. All that social data can only improve Google's services. And G+ blunts any advantage that FB has. All good things. The downside is that people (particularly devs) hate when their existing services change. Also, G+ has never offered a compelling reason to switch, and few people are going to manage 2 identical social networking accounts. Google will have to build/buy something great, as they did with Maps & Mail, to attract users to G+. Otherwise, it's Buzz and Orkut all over again.
