Introducing the Internet Topic Exchange
Phillip Pearson is in the process of creating the Internet Topic Exchange (http://topicexchange.com). This is a service that enables anyone to easily create blog channels like Lazyweb.org, Blogpopuli, and KMPings. Once a channel is set up, people can send links to their weblog posts to it using TrackBack or using a simple form. The resulting feeds can be read on the web and they are also available as RSS. To see what it looks like, have a look at the new "Down and Out in the Magic Kingdom" channel.
Matt Mower: "What Phil has done is to implement a very simple, elegant, solution along the path of the BlogPlex idea I've been working towards. With the Topic Exchange, it will be simple for users to cluster around topics simply by using them."
This is indeed, I believe, a good way to facilitate group-forming among bloggers. Hopefully, people will set up channels corresponding to interests close to their heart and will subscribe to them. As I have pointed out earlier, this is a sociality-driven way of building what has been called "shared categories", "shared topics", or "distributed metadata".
One way to see it is that this extends the notion of RSS feeds. An ordinary RSS feed is easy to listen to, but "hard" to speak into. Blogchannels correct the asymmetry by making it easy both ways. Phillip has also put up what he calls a vague history of the concept.
