Jon Udell: Social networking in Radiospace Weblogs often list affiliated weblogs as a column of links which Doc Searls first named a blogroll. A couple of months ago, on my Radio weblog, I tried a variation on this idea. Rather than hand-edit my blogroll, I wrote a script that automatically reads the list of RSS channels to which I subscribe, in Radio's news aggregator, and echoes that list on my homepage. With a tip of the hat to Doc, I called this widget a channelroll.
