Ethan Zuckerman blogs about the future of advocacy.  He demonstrates a shift from programmatic "representation" to the "pointing and contextualizing" of the blog world.  This amplifies an important lesson regarding "tolerance."  Just as it is embarassingly presumptuous to emphasize "tolerance" as a value (who am I to presume to tolerate you!?), so also is the tendency idealistically to adopt-a-cause and represent the less fortunate who come along with the ideal.
