One of my favorite aggregation sites is Business Week Exchange. To me BX represents a knowledge inventory. Everyone who posts to this site is a media maven, social influencer, and trust agent. Each one represents a galaxy of relationships, experiences, and followers. All the categories are sourced by these users. All of the articles are sourced and often written by these users. All the trending data are produced by the users. By far, my highest QUALITY followers come from BX; not Twitter, not Facebook, and not Friendfeed.
