Oh, I think I misread that, but it&#x27;s slightly ambiguous - are we restricting <i>blocking</i> to specific people (Aunt Susan is uptight and shouldn&#x27;t see my posts) or are we restricting <i>post visibility</i> to specific people? I guess Dylan probably meant the latter...<p>I disagree that the failure of Google+ means that nobody wants privacy settings, or in general that the failure of a business means that every single minor innovation they made was flawed.  Google+ failed because of the network effect - a social network is only useful if it&#x27;s also used by people you want to socialize with.<p>People consistently list privacy controls as among their biggest problems with Facebook, and circles solved that problem neatly once people figured out how they worked.  You can of course replicate a circle with a user list on Facebook, but it&#x27;s nowhere near as obvious.
