Google+ has a significantly more powerful API for its trusted partners, such as Hootsuite. And maybe Buffer, unless they are doing some headless browsing hacks.

Google+ has a significantly more powerful API for its trusted partners, such as Hootsuite. And maybe Buffer, unless they are doing some headless browsing hacks. Their public API is read only for strategic reasons. Unless you have a clear business case or plan on how to monetize APIs, opening them up can actually backfire very easily. The biggest example of this is Twitter itself, which has been trying to lock down its APIs since they are basically losing both money and direct access to users through them. But closing them now is causing further hurt, on user trust and goodwill.
