&gt; I really don&#x27;t like to marginalize others by what type of personality they are.<p>Me either, I hope that&#x27;s not what it sounded like.<p>&gt; Before facebook people would keep large collections of photo books so that when family and friends came over they could easily share them. It doesn&#x27;t mean they valued those pictures any less because they were extroverted vs. introverted. People still keep hard copies of the pictures they cherish the most, like a wedding album.<p>Yeah, absolutely, and I think people do still keep the photos they care most about today. I just think we overestimate how many of those photos exist. I think the overwhelming use of taking photos is for social conversation.
