When I wrote this article I started from a belief that by combining Denham’s thoughts with my earlier post I had seen a new aspect of the possibilities for knowledge aggregation and filtering.
Then I read the background links that led to this addition, added in a spirit of “Oh, perhaps it wasn’t that original after all, I’d better acknowledge this other work”. In other words some of the glow of achievement I felt about spotting the earlier idea had been tarnished.
Today via Phil Jones’ wiki I found this David Weinberger post from a few years ago which has restored some of the good feelings – others may have had a similar idea before but that doesn’t reduce the value to me of the new-to-me thought.
