High Trust Environments- Tech Central Station

Quote: Which is why the Blogosphere's tail is often a place of great influence. In an interview Hewitt told me, 'I would rather have 90 percent of the blogs and none of those top ten percent bloggers writing about my book, than I would have all of the top ten percent and none of the 90 percent doing so. Because the 90 percent of the tail operate in very high trust environments: they're read by their brother in law, they're read by their neighbors, their friends in church, their friends at work. If they say, 'hey you ought to read this book', it'll sell a lot of books!'

Via Instapundit, who is not in the tail.
