The Six Pillars of Blogging

According to the book "Naked Conversations" by Robert Scoble and Shel Israel, the "Six Pillars of Blogging" are

1. Publishable. Anyone can publish a blog. You can do it cheaply and post often. Each posting is instantly available worldwide.
2. Findable. Through search engines, people will find blogs by subject, by author, or both. The more you post, the more findable you become.
3. Social. The blogosphere is one big conversation. Interesting topical conversations move from site to site, linking to each other. Through blogs, people with shared interest build friendships unrestricted by geographic borders.
4. Viral. Information often spreads faster through blogs than via a news service. No form of viral marketing matches the speed and efficiency of a blog.
5. Syndicatable. By clicking on an icon, you can get free "home delivery" of RSS-enabled blogs. RSS lets you know when a blog you subscribe to is updated, saving you search time. This process is considerably more efficient than the last-generation method of visiting one page of one web site at a time looking for changes.
6. Linkable. Because each blog can link to all others every blogger has access to millions of other bloggers.
