Sich in virtuellen Interessengemeinschaften abschotten

Tim Challies drückt aus, was ich selber als Gefahr erkenne: Internet, FB und Konsorten geben die Möglichkeit, sich in virtuellen Interessengemeinschaften abzuschotten:

The Internet has allowed us to expand our understanding of community so that we can have significant and ongoing interaction with people regardless of their location. Today my sense of belonging, my sense of identity, may be tied most closely to a community of people who share an interest but who relate only online. I may feel closer affinity with these people than with anyone in my own zip code or my own local church. Many of us have custom-built a community for ourselves based around a common interest.
