daily word - size of your circle?

How effectively are you able to limit your circle of contacts to those who are similar to yourself? This is possible now more than ever before. Increased mobility and electronic communications can open you to a broader world, or allow you to find and associate with an ever more narrowly defined community. Do you think that this is beneficial? How often do you have real encounters with those of substantially different beliefs, professions, political opinions, education and income level from yourself? Who would decline the benefits of affluence and technology? Yet are these things making your world larger or smaller?
