Enabling and Reflecting: helping them "do their thing" their way, and creating iconography that feels "homey". Do users love sharing content? Consider UI/UX approach to share ability of content, usability of sharing buttons. Reflecting includes subtle cues : your choice of vectors, colors, even a demographic appropriate sense of humor in the naming of buttons and links. I read about how even a 404 error page should be included thematically. Remember: you set a culture, but if you get users, they will own it!
