At some point (probably one we’ve already passed), weblog technology will be seen as a platform for so many forms of publishing, filtering, aggregation, and syndication that blogging will stop referring to any particularly coherent activity. The term ‘blog’ will fall into the middle distance, as ‘home page’ and ‘portal’ have, words that used to mean some concrete thing, but which were stretched by use past the point of meaning.
