But blogs accomplish public discussion through a far different architectural design pattern. In the Well's terminology, taken to its extreme, you own your own words. If someone on a blog "posts a topic", others can respond, but generally do so in their own  blogs, hyperlinked back to the topic's permalink. This goes on and on, back and forth. In essence, it's the same hyperlinking mechanism as the traditional discussion design pattern, except that the topics and responses are spread out all over the Web. And the reason that it "solves" the signal:noise problem is that nobody bothers to link to the "flamers" or "spammers", and thus they remain out of the loop, or form their own loops away from the mainstream discussion. A pure architectural solution to a nagging social issue that crops up online.
